Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a structure for preventing curtain inclusion of a window shutter for a house.

[Problems to be Solved by Prior Art and Invention] In general, this type of window shutter for a house has weaker slat strength constituting each shutter curtain than a lightweight shutter for other stores, and the inertia force when the shutter is opened and closed. As a result, the curtain bends in the front-back direction and rises and falls when the center of the curtain is covered. Therefore, as shown in Fig. 1, a space is placed at a position farther to the outside than the shutter guide rail. Therefore, it is not possible to directly regulate the entrainment of a window shutter for a house when the curtain is rolled up on a seat plate, and at a site that extends outside the seat plate drainer. It is necessary to separately provide a long stopper S that abuts against the lintel.

By the way, conventionally, the elongated stopper S has been shown in FIG.
As shown in FIG. 2, the lateral movement of the shutter curtain a is regulated at the upper part of the drainage portion C of the seat plate b connected to the lower end edge of the shutter curtain a having both ends fitted to the guide rails, and at the time of winding. In order to prevent the drainage part of the shutter curtain from being caught in the lintel, they are attached to both ends of the seat plate vertical part d in a cantilevered state.

Therefore, when the shutter curtain is rolled up, the drainage part is prevented from being rolled up, but the impact load at the lintel e is prevented by the stopper S.
Since it is received only by itself, the stepper mounting rivet or the screw may be loosened by repeated impacts, and the stopper and the seat plate may be significantly damaged.

On the other hand, in addition to the problem caused by the impact load of the stopper, in the fully opened state of the shutter curtain a, that is, in the contact state of the stopper e, the lintel e and the seat plate drainer c are largely separated from each other. It may be unsightly because it makes it difficult to open and close the shutter, for example, relatively large animals such as birds invade the shutter case from the space formed in the lintel on the outdoor side of the guide rail to create a nest. There were problems such as trouble.

[Means for Solving Problems] The present invention was devised in view of the above circumstances to provide a structure for preventing the inclusion of a curtain in a window shutter for a house that can eliminate these problems. The purpose of the shutter is a seat plate that is formed by integrally molding a vertical portion and a water draining portion that extends outwardly from the lower end of the vertical portion in an L shape and bends the tip side downward. Connected to the lowermost stage of the curtain, cut out both ends of the water draining part of the seat plate so that it is shorter than the distance between the guide rails facing each other on the left and right, and the shutter curtain and the guide rail and the upper lintel of the opening. In a window shutter that moves up and down along a section, the vertical fixing section fixed to the vertical section of the seat plate has a top surface that is horizontal and a bottom surface that is in surface contact with the top surface of the draining section, and that extends outward from the draining section. Let vertical fixed The hook contacting part attached to the lower end of the part, and a plurality of reinforcing ribs provided between the vertical fixing part and the hook contacting part, make a stopper that is uniformly molded, and make a surface contact with the upper surface of the draining part. By adopting a configuration in which the vertical fixing part of the stopper is attached to the vertical part of the plate,
Although the curtain roll-up is regulated when the shutter is rolled up at a location that protrudes from the seat plate, the impact load applied to the hook contact part of the stopper that regulates the roll-up is such that the vertical fixing part does not contact the seat plate. With the organically connected structure, not only the vertical portion of the seat plate but also the entire drain plate of the seat plate receives and distributes the impact force, preventing the risk of loosening the stopper mounting screws and the damage of the stopper itself or the seat plate. It is possible to reduce the distance between the drainage part of the seat plate and the lintel when the shutter curtain is wound up due to the presence of a stopper provided separately from the seat plate, and thus the space formed in the lintel part e. It is a good idea to block the seat board drainer 2b and provide a good appearance. In the shutter case, the bird is drawn from the space formed in the lintel part on the outdoor side of the guide rail. It prevents a relatively large animal invasion, in which to be able to permanently secure the smoothness of the shutter opening and closing operations have.

[Embodiment] Next, one embodiment of the structure for preventing curtain inclusion of a window shutter for a house according to the present invention will be specifically described with reference to the accompanying drawings.

1 is a shutter curtain, this shutter curtain 1
A vertical portion 2a and a draining portion 2b in which the tip end side is bent downward are integrally formed at the lower end edge of the vertical portion 2a and the lower edge of the vertical portion 2a with a slight outward gradient. The upper edge of the vertical portion 2a of the seat body 2 is connected.

The draining portion 2b of the seat plate 2 is cut out at both ends so as to be shorter than the space between the guide rails 3 which are vertically provided facing the left and right sides of the window, and the vertical portion 2a of the seat plate 2 together with the shutter curtain 1 is guided by the guide rails 3,3. It is fitted so that it can be raised and lowered.

Reference numeral 4 denotes a stopper attached to the seat plate 2. The stopper 4 is a vertical fixing portion 4b attached to the vertical portion 2a of the seat plate 2 and the stopper plate 4 is projected to the outdoor side from the seat plate 2 so that the upper surface is horizontal. It is integrally formed with the lintel contact portion 4c in a substantially L shape, and the vertical fixing portion 4b and the lintel contact portion 4c are reinforced by a plurality of reinforcing ribs 4a, 4a. Further, the stopper 4 is integrally provided with an overhanging portion 4d that covers an edge portion of the draining portion 2b of the seat plate 2.

Then, the stopper 4 makes the bottom surface of the vertical fixing portion 4b come into surface contact with the upper surface of the end portion of the seat plate draining portion 2b so that the overhanging portion 4d covers the edge of the draining portion 2b and the lintel contact portion 4c.
The bottom surface of the seat is brought into surface contact with the top surface of the draining part 2b, and the vertical fixing parts 4b are attached and fixed to the right and left ends of the seat plate 2 by screws or rivets 5 on the seat plate vertical part 2a. The overhanging portion 4d that covers the edge of the draining portion is also used as a regulating portion that regulates the left and right shake of the shutter curtain 1.

[Operation] In the embodiment of the present invention configured as described above,
When the shutter curtain 1 in the closed posture is opened, the stopper 4 attached to the seat plate 2 connected to the shutter curtain 1 hits the lintel portion e provided on the outdoor side of the guide rail 3 and the shutter curtain 1 In the structure for preventing the shutter curtain 1 from being rolled up, the bottom surface of the vertical fixing portion 4b of the stepper 4 and the lintel contact portion 4C are provided on the upper surface of the draining portion 2b of the seat plate 2. The bottom surface of the is fixed by surface contact, and the vertical fixing portion 4b
And a stopper 4 which is formed integrally with the vertical fixing portion 4b and the upper surface horizontal lintel contact portion 4c which extends outward from the seat plate 2 and contacts the upper lintel portion e of the opening.
However, since the vertical fixing portion 4b is attached and fixed to the vertical portion 2a of the seat plate 2, the curtain 1 at the time of winding the shutter 1
The impact load applied to the horizontal lintel contact portion 4c of the stopper 4 that regulates the entanglement is fixed to the seat plate 2 while the entanglement restriction is performed at a portion of the seat plate 2 that protrudes beyond the draining portion 2b. The vertical fixing portion 4b can be received not only by the vertical portion 2a of the seat plate 2 but also by the entire seat plate of the draining portion 2b by the organic coupling structure with the seat plate 2. The impact force applied to the stopper 4 is more surely dispersed as compared with the case where the stopper 4 is fixed to only 4a, and the risk of loosening of the stopper mounting screw or the like and damage of the stopper 4 itself or the seat plate 2 can be prevented. .

Further, when the shutter curtain 1 is fully opened, the hood contact portion 4c and the lintel portion e of the stopper 4 are in contact with each other, and the lintel portion e and the seat plate water drain portion 2b are separated from each other. However, in the structure for preventing the shutter curtain 1 from being rolled up in this embodiment, the stopper 4 described above is used.
Due to the mounting structure of the vertical fixing portion 4b of the seat plate 2 to the vertical portion 2a of the seat plate 2, the lintel contact portion 4c projected to the outdoor side from the seat plate drainer 2b is more than the conventional drainer 2b. Since it is configured to be closer to the lintel portion e, the distance between the seat plate draining portion 2b and the lintel portion e can be reduced when the shutter curtain 1 is rolled up, and thus the lintel portion e
Perhaps it is possible to provide a good appearance by closing the space part formed in the seat plate draining part 2b, and as in the conventional case, from the space formed in the lintel part e in the shutter curtain 1, from the bird etc. It is possible to prevent a relatively large animal from entering, and thus it is possible to smoothly open and close the shutter.

Further, in the lower surface area of the lintel contact portion 4c of the stepper 4,
Since the reinforcing structure is adopted by providing the plurality of reinforcing ribs 4a, the strength can be further improved.

Furthermore, since the edge of the water draining portion 2b is covered with the overhanging portion 4d of the stopper 4, the left and right runouts of the shutter curtain 1 when the shutter curtain 1 is raised and lowered are received by the guide rails 3 to reliably control the runout. It can also be used as a restricting part to perform, and therefore durability can be obtained without generating contact noise.

[Effects] In summary, the present invention is a stopper that is attached to the bottom seat plate of the shutter curtain and prevents the curtain of the window shutter that comes into contact with the lintel provided on the outdoor side of the shutter guide rail. The stopper, and a vertical fixing portion whose bottom surface is fixed to the upper surface of the draining portion of the seat plate by surface contact, and extending from the vertical fixing portion to an outside of the seat plate draining portion, and the lintel portion. It is constructed by integrally forming a lintel contact part that comes into contact with the seat, and the vertical fixing part of this stopper is attached to the vertical part of the seat plate. By arranging on the upper surface of the seat plate draining part so that the space between the sword and the lintel are close to each other, the space formed in the lintel e is closed by the seat plate draining part 2b, which is favorable. Can provide a look In addition, by closing the space portion, it is possible to prevent a relatively large animal such as a bird from entering the shutter case from the space, so that the shutter opening / closing operation can be smoothly performed. Also, while the curtain roll-up is regulated when the shutter is rolled up at a location where it protrudes from the water draining part of the seat plate, the impact load applied to the lintel contact part of the stopper that regulates the roll-up is The vertical fixing part to be fixed is not only the vertical part of the seat plate due to the organic coupling structure with the seat plate, but also the whole draining part of the seat plate receives the impact force to loosen the stopper mounting screw etc. and the stopper itself or the seat. It is possible to prevent the risk of plate damage.
