[0001]
BACKGROUND OF THE INVENTION
The present invention provides a shutter for a building constructed by connecting a large number of lateral slats.
[0002]
[Prior art]
For example, as shown in FIG. 1, a shutter of a building constructed by connecting a large number of lateral slats is for windows made up of left and right vertical frames 2, 2, a lower frame 3, and an upper frame 4. It is provided so that the outdoor side of the rectangular frame can be opened and closed. A top plate 5 is attached to an upper portion of the upper frame 4 of the rectangular frame, and a shutter case is provided in which a shutter S is wound and accommodated via a back plate 6 in the front portion of the area between the upper frame 4 and the top plate 5. 7 is fixed, and the shutter case 7 is supported from below by left and right vertical guide rails 8 and 8. The guide rails 8 and 8 are configured to guide left and right edge portions of the shutter S that is drawn downward from a shutter winding shaft (not shown) in the shutter case 7. The front surface of the shutter case 7 is closed by a cover 9.
[0003]
The shutter S is configured by connecting a large number of lateral slats 10 in series. FIG. 6 shows the structure of the slats 10 adjacent in the vertical direction. Each slat 10 has a hollow plate-like long main body 11, and a partition wall 12 is integrally formed in the middle of the main body 11.
[0004]
Further, the upper side wall 13 of the main body 11 constitutes a support surface that comes into contact with the lower side wall 14 of the slat 10 adjacent to the upper side thereof. A suspension base 16 is integrally provided upward from the upper side wall 13. The suspension 16 has a plate-like portion 17 inclined at the tip. In addition, a relatively narrow slot 18 is formed in the lower wall 14 of the slat 10 so as to extend in the lateral direction of the slat body 11. The space between the long hole 18 and the partition wall 12 constitutes a hollow fitting portion 19.
[0005]
In the assembled state of the shutter S, the lower slat suspension 16 is inserted into the hollow slat fitting portion 19 of the upper slat as indicated by a virtual line from below. Since the plate-like portion 17 of the suspension base 16 is larger than the long hole 18, the suspension base 16 is prevented from dropping downward through the slot 18.
[0006]
When the shutter S is in the fully closed state, as shown in FIG. 7A, the slat 10 is supported in contact with the upper side wall of the lower slat 10, and the suspension 16 of the lower slat 10 is supported by the upper slat 10. Is completely buried in the hollow fitting portion 19. In this state, the weight of the upper slat 10 and all the slats higher than the upper slat 10 are supported on both sides of the suspension base 16 of the upper side wall 13 of the lower slat 10. On the other hand, when the shutter S is in a semi-closed state, the suspension base 16 of the lower slat 10 is partially removed from the hollow fitting portion 19 of the upper slat 10 as shown in FIG.
[0007]
[Problems to be solved by the invention]
By the way, in the conventional shutter described above, the lower slats 10 bear the load of the upper slats 10 in the fully closed state shown in FIG. Can no longer withstand the load and undulate in a zigzag manner. The reason is that the lower slat hanger 16 can move left and right in the hollow fitting portion 19 including the plate-like portion 17 at the tip as viewed in FIG. Since the long hole 18 through which the base of the suspension base 16 is inserted has a narrow width, the suspension base 16 is easy to rotate around the portion passing through the long hole 18. Therefore, the adjacent slats are zigzag by this rotation. It is easy to wave in the state. Such a zigzag state is not preferable because the shutter in the fully closed state looks bad, and when the wind is strong, the slats are displaced from each other in the zigzag state to generate a rubbing sound.
[0008]
The present invention has been made to solve the above-described problem, and even in a fully closed state, adjacent slats do not undulate in a zigzag state, and therefore, the appearance is good and the rubbing noise is generated even when the wind is strong. It is an object to obtain a shutter for a building that cannot be done.
[0009]
[Means for Solving the Problems]
According to the present invention, the above-mentioned problem is composed of a plurality of slats arranged in the vertical direction, and each slat has a suspension base projecting upward along the upper side wall of the main body and along the lower side wall of the main body. In a shutter of a building having a hollow fitting portion that is recessed in the upper side, and a suspension base of a slat adjacent to the lower side is engaged in the hollow fitting portion from below, the partition wall at the upper end of the hollow fitting portion On the lower side, a protrusion is formed on which the leading end of the suspension engaged with the inside of the hollow fitting portion contacts, and the leading end of the suspension forms a plate-like portion having an inclined contact surface. The protrusion has an inclined surface that contacts the inclined contact surface of the suspension tip, and the inclined contact surface is curved toward one side in the shutter inside and outside of the hollow fitting portion. In the fully closed state of the shutter, the inclined contact surface of the suspension base tip is the Together abuts against the inclined contact surface of the output portion is achieved by the upper wall of the lower slat body adjacent vertically support the slats of the upper in contact total of three locations in the lower wall of the slats of the upper.
[0010]
Further, on the side where the inclined contact surface of the protruding portion is provided close to one side of the hollow fitting portion in the shutter inside / outside direction, the lower side wall of the upper slat and the upper side wall of the lower slat are connected to the protruding portion. It is preferable to form an inclined surface in the same direction as the inclined contact surface.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 2 shows the half-closed state of the shutter of the building according to the present invention, and FIG. 2 shows the fully-closed state of the shutter of the building according to the present invention. In these drawings, the same reference numerals are given to the portions equivalent to the shutter of FIG. 5 which is the conventional example.
[0012]
2 and 3, the shutter S is configured by connecting a large number of lateral slats 10 in the vertical direction. In the description of the present embodiment and in the claims, “upper” and “lower” refer to the case where the shutter S is pulled out from the entrained state downward to the substantially vertical state shown in FIGS. Means "upper" and "lower" in
[0013]
Each slat 10 has a hollow plate-like long main body 11, and a partition wall 12 is integrally formed in the middle of the main body 11. Further, the upper side wall of the main body 11 constitutes a support surface that comes into contact with the lower side wall of the slat 10 adjacent to the upper side thereof. A hanging base 16 is integrally projected upward from the upper side wall, one side of the hanging base 16 is a first upper side wall 13a, and the other side is a second upper side surface 13b. . The first upper side wall 13 a is formed as an inclined surface that descends toward the side surface of the main body 11.
[0014]
The suspension base 16 has a plate-like portion 17 having an inclined surface at its tip. The inclination direction of the inclined surface of the plate-like portion 17 is the same as the inclination direction of the first upper side wall 13a. Further, as shown in an enlarged view in FIG. 4, an elongated hole 18 having a relatively narrow width is formed in the lower side wall of each slat 10 so as to extend in the longitudinal direction of the slat body 11. The first lower side wall 14a on the first upper side wall 13a side with respect to the long hole 18 is formed as an inclined surface 20 corresponding to the first upper side wall 13a of the slat 10 adjacent to the lower side. . A second lower side wall 14 b is provided on the opposite side of the long hole 18. The space between the long hole 18 and the partition wall 12 constitutes a hollow fitting portion 19.
[0015]
According to the present invention, the protruding portion 21 is formed on the lower side of the partition wall 12 in the hollow fitting portion 19. The projecting portion 21 is designed so as to abut on the inclined surface of the plate-like portion 17 of the hanging base 16 that engages in the hollow fitting portion 19. That is, in the shutter fully closed state in which the upper side wall of the lower slat body 11 adjacent to the upper and lower sides is in contact with the lower side wall of the upper slat body 11 to support the upper slat, the protrusion 21 is a plate of the suspension base 16. The plate portion 17 is designed to have a shape that abuts the inclined surface of the shape portion 17 and prevents the plate portion 17 from being displaced in the thickness direction of the shutter S. More specifically, the plate-like portion 17 that is the tip portion of the hanging base 16 is configured as a plate-like portion having an inclined contact surface, and the protruding portion 21 is an inclined surface 22 that comes into contact with the inclined contact surface of the hanging base 16. It is designed to have
[0016]
In the assembled state of the shutter S, the suspension base 16 of the lower slat 10 is inserted into the hollow fitting portion 19 of the upper slat 10 from below as shown in FIG. And since the plate-shaped part 17 of the hanging base 16 is larger than the long hole 18, the hanging base 16 does not fall through the long hole 18 downward.
[0017]
When the shutter S is in the fully closed state, as shown in FIGS. 3 and 5, the slat 10 is supported in contact with the upper side wall of the lower slat 10, and the suspension 16 of the lower slat 10 is supported by the upper slat 10. Is completely buried in the hollow fitting portion 19. In this embodiment, the upper side wall of the slat 10 has a first upper side wall 13a that is inclined, and the first lower side wall 14a of the upper slat 10 has a slope with respect to the inclined surface of the first upper side wall 13a. It is designed so that the inclined surfaces abut. Therefore, when the first lower side wall 14a of the upper slat 10 exerting a load on the lower slat 10 slides down with respect to the first upper side wall 13a of the lower slat 10, the second lower side on the opposite side is lowered. The tip of the side wall 14b comes into contact with the surface of the suspension base 16, and the sliding of the upper slat 10 stops there. In this state, the weight of the upper slat 10 and all the slats higher than the upper slat 10 are supported by the upper side walls 13a and 13b of the lower slat 10.
[0018]
In this state, the tip of the suspension base 16 is configured as a plate-like portion 17 having an inclined contact surface, and the protruding portion 21 has a convex curved inclined surface 22 that contacts the inclined contact surface of the suspension base 16. Since it is designed, in the fully closed state of the shutter S, the inclined contact surface of the plate-like portion 17 of the hanging base 16 that is pushed into the innermost portion of the hollow fitting portion 19 is the convex curved slope of the protruding portion 21. It abuts on the surface 22 as shown in FIGS. Then, the inclined surfaces abut on each other in this manner, so that the plate-like portion 17 of the hanging base 16 is prevented from being displaced in the thickness direction of the shutter S (the right direction in FIGS. 3 and 5).
[0019]
Therefore, the slats 10 adjacent to each other in the upper and lower directions are contact portions between the plate-like portion 17 of the suspension base 16 and the projecting portion 21, contact portions by the first upper side wall 13a and the first lower side wall 14a, By the support at the three locations of the abutment location by the upper side wall 13b and the second lower side wall 14b, they are securely fixed to each other so as not to wave in a zigzag state. Accordingly, it is possible to prevent the shutter S from making a rubbing sound with rattling due to wind or the like.
[0020]
In addition, the inclined contact surface 22 of the protruding portion 21 is formed in a convex curved shape by moving toward one side of the hollow fitting portion 19 in the shutter inner / outer direction, so that the contact with the protruding portion 21 of the suspension tip portion 17 is achieved. Connection and withdrawal are performed smoothly. Further, by forming the 21 inclined contact surface 22 of the protruding portion toward one side of the hollow fitting portion 19 in the inner and outer directions of the shutter so as to form a convex curved surface, the protruding portion 21 in the hollow fitting portion 19 is formed. Arrangement becomes rational, and contact and separation with the protruding portion 21 of the suspending tip portion 17 are smooth and easy. Further, in the fully closed state of the shutter shown in FIG. 5, even when the lower slat 10 tries to rotate clockwise with respect to the upper slat 10, the suspending tip 17 contacts the protruding portion 21 as described above. In addition, when the tip of the lower side wall 14b of the upper slat 10 abuts on the base portion of the suspension base 16, clockwise rotation is prevented. On the other hand, even if the lower slat 10 tries to rotate counterclockwise with respect to the upper slat 10 in a direction in which the suspension tip is separated from the protrusion, the lower slat 10 is inclined to the inclined lower side wall 14a of the upper slat 10. By pressing the upper side wall 13a, the counterclockwise rotation of the lower slat 10 is also prevented. This effect is further ensured by the fact that the upper side wall 13a and the lower side wall 14a are inclined surfaces. Therefore, the slats are reliably prevented from undulating in a zigzag manner.
[0021]
On the other hand, in the semi-closed state shown in FIG. 2, the suspension base 16 of the lower slat 10 is at least partially removed from the hollow fitting portion 19 of the upper slat 10. In the case of a design in which a lateral slot is formed on the surface of the suspension base 16, the inside and outside of the shutter communicate with each other through this slot, and the shutter is in a semi-closed state.
[0022]
【The invention's effect】
As described above, according to the invention of claim 1, even when the shutter is fully closed, adjacent slats do not swell in a zigzag state, and thus, the appearance is good and the wind is strong. No rubbing sound is generated. In the first aspect of the invention, the tip of the suspension base is configured as a plate-like portion having an inclined contact surface, and the protrusion has an inclined surface that contacts the inclined contact surface of the suspension base. Thus, it is possible to ensure the contact between the protruding portion and the suspension base. Furthermore, by arranging the inclined contact surface of the protruding portion toward one side of the hollow fitting portion toward the inside and outside of the shutter so as to form a convex curved surface, the arrangement of the protruding portion within the hollow fitting portion is rational. Thus, the contact and detachment with the protrusion at the tip of the suspension base are smooth and easy.
[0025]
Furthermore, in the invention of claim 2 , the lower side wall of the upper slat and the upper side wall of the lower slat are provided on the side where the inclined contact surface of the protrusion is provided close to one side of the hollow fitting portion in the shutter inner / outer direction. Is formed as an inclined surface in the same direction as the inclined contact surface of the projecting portion, so that the suspension tip of the lower slat is prevented from being displaced in a direction away from the projecting portion of the upper slat.
