  Movable louvers are well recognized for their design advantages in addition to their functional superiority in daylighting and ventilation, but traditionally they are often used for crime prevention such as armor doors and FiX windows, most of which are aluminum sashes. However, nowadays, there is a tendency for products that do not limit the application location and purpose as customer needs diversify. For example, a typical example is a wooden movable louver, but we are planning a series of innovative movable louvers that combine several different materials, such as a metal cage such as aluminum or stainless steel with glass movable wings. Has been. However, as a problem when expanding the applicability of movable louvers, this type of movable louver requires more thickness than ordinary fittings, and operation units and levers for changing the louver are opened. Because of this, it can be applied only to doors that do not place strict limits on the wall thickness of fixtures, or to fixtures such as Fix that can fit in the opening, and generally have high customer needs. Application to such as was postponed. In addition, when a wooden movable louver is placed in a relatively busy place such as an entrance and exit, there are many opportunities for people and objects to contact the louver unexpectedly. Due to this, in the case of wooden movable louvers that are easily scratched, the movable wings may need to be replaced depending on the degree of damage. In such cases, the operation unit has a complicated structure after disassembling the movable louvers. General users who do not have specialized knowledge must entrust to the manufacturer, and even one manufacturer has a complicated structure. However, the current situation is that efficient production has not been achieved.

  The present invention has been made in view of the above problems, and provides a movable louver that is excellent in operational feeling when opening and closing movable wings, has a simple structure, and can be applied to various indoor and outdoor openings. There is to do.

According to the invention described in claim 1 of the present invention, one end portion in the longitudinal direction of the shaft body of the movable blade is engaged with the operation portion, and the other end portion in the longitudinal direction is the side end surface of the movable blade. The movable wings can be easily taken out from the main body of the movable louver by being engaged in a freely detachable manner. In addition, the end of the shaft body on the side inserted into and removed from the side end surface of the movable blade is engageable with the depth of the bearing hole, so that the rotational force is reliably applied to the movable blade when the shaft body rotates. As a result, this kind of movable louver, which has been complicated in the past, can be made simple and increase the productivity on the manufacturer side, and the movable louver can be placed in various openings with a free layout. be able to.

  According to the third aspect of the present invention, since the transmission racks are provided on the front side and the rear side of the coaxial gear, when the coaxial gear rotates, one transmission rack moves upward. Since the other transmission rack moves downward, the rotation angle of the movable blade can be firmly positioned at an arbitrary angle desired by the user.

  According to the invention described in claim 4 of the present invention, the movable wing is moved by the locking shaft on the side opposite to the side on which the rotating shaft of the movable wing is inserted protrudes toward the left and right vertical shafts. The rotating shaft body comes out of the movable wing by approaching the left and right vertical shafts on the side where the locking shaft body is inserted. As a result, the movable blade can be easily replaced, and the labor required for maintaining the movable louver after the introduction is reduced, and the maintainability is improved.

Hereinafter, embodiments of a movable louver according to the present invention will be described with reference to the drawings.
FIG. 1 is a partially cutaway front view showing the entire movable louver of the present invention, FIG. 2 is an enlarged perspective view showing A in FIG. 1, and FIGS. FIG. 3 is a cross-sectional view taken along line BB in FIG.
In addition, the movable louver by this implementation demonstrates a wooden thing.

  The overall structure of the movable louver according to the present invention will be described. As shown in FIG. 1, between the upper eaves 2 and 3 installed in the indoor opening L of the building, and between the left and right vertical eaves 1a and 1b arranged parallel to the left and right. In addition, a plurality of movable blades 4 are supported by a horizontal rotary shaft 5 so as to be rotatable in a horizontal axis at equal intervals in the vertical direction, and further, the tip of each rotary shaft 5 on the side that enters the right vertical shaft 1a. Each has a coaxial gear 8 that rotates in the same direction as the rotary shaft 5. The right vertical rod 1a has a U-shaped cross-section, and the space S in the left and right vertical rod 1a will be described in detail later, but transmission racks 7a and 7b related to opening and closing of the movable blade 4 are stored. The transmission racks 7a and 7b rotate all the movable blades 4 in the same direction at the same time in the horizontal direction by the operation of the user.

As shown in FIGS. 2 and 3, the part of the movable louver related to the opening and closing of the movable wing 4 meshes with the coaxial gear 8 of the movable wing 4 and extends vertically along the longitudinal direction of the right vertical shaft 1a. The rack 7a, 7b, a knob 9 that moves the transmission racks 7a, 7b up and down, and a casing 18 that fixes the knob 9 and the transmission rack 7b.
As shown in FIG. 4, the transmission racks 7a and 7b are attached via a rack holding member 10 having a rectangular cross section in the right vertical shaft 1a according to the present embodiment. 10, the transmission racks 7 a and 7 b are arranged so as to be continuous in the vertical direction across the front side and the back side of all the coaxial gears 8 that have entered the inside of the right vertical shaft 1 a and the rack holding member 10. Each of the transmission racks 7a and 7b is mounted so as to be movable up and down along guide grooves 11 and 11 provided on the front side and the back side inside the rack holding member 10.
The upper and lower ends of the guide grooves 11 and 11 are respectively provided with stoppers that block the upper and lower ends of the guide grooves 11 and 11, and the transmission racks 7 a and 7 b are guided by the guide grooves 11 by regulation of the stoppers. , 11 does not move up and down. Thus, when the knob 9 is moved upward or downward, the transmission racks 7a and 7b move in opposite directions (specifically, if one moves upward, the other moves downward) Since the other transmission racks 7a and 7b are always restricted from rotating in the opposite direction with respect to the rotation of the coaxial gear 8 in one direction by the transmission racks 7a and 7b, the movable blades 4 are variable as desired by the user. It is designed to stop at an angular position, and to perform subtle angle adjustments when taking light or taking in wind.

As shown in FIG. 2, the rotary shaft body 5 has a coaxial gear 8 that meshes with the transmission racks 7 a and 7 b at the left end portion in the extending direction of the rotary shaft body 5. 4 has an insertion portion 21 that can be inserted into a bearing hole 23 provided on the side end surface of the first side. This insertion portion 21 is provided with a pair of notches 21a and 21a at two opposite positions orthogonal to the axial direction at the right end portion of the rotating shaft 5 that rotates horizontally. And an engaging portion 22 having a substantially rectangular cross section. Then, when the coaxial gear 8 is rotated, an engaged portion 25 is provided in which the depth of the bearing hole 23 forms a stepped hole portion in the same manner as the engaging portion 22 of the insertion portion 21. The engaging portion 22 of the portion 21 is firmly engaged with the inside of the bearing hole 23 on the right end surface of the movable blade 4. When formed in this way, the coaxial gear 8 can be prevented from idling when the knob 9 is moved up and down, and the rotational force can be reliably transmitted to the movable blade 4. Further, since the rotating shaft body 5 is integrally formed with the coaxial gear 8, the labor of assembling the movable louver is greatly reduced, and the movable portion of the movable blade 4 has a simple structure. In the case of a movable louver having a complicated structure with a large number of parts in the movable part, it is presumed that the production delivery time is shortened and the maintainability of the product after delivery is expected to be improved.

FIG. 4 shows another embodiment of the rotary shaft body 5 of the present invention.
In FIG. 4 , the engaging portion 22 a is formed in a substantially hexagonal shape, and an engaged portion 25 a having a substantially hexagonal hole shape corresponding to the engaging portion 22 a is formed at the back of the bearing hole 23. It is provided. Also by forming in this way, the rotation angle can be adjusted without the rotating shaft body 5 engaging with the side end face of the movable blade 4 and idling.

Further, as shown in FIG. 3 , a locking shaft body 26 that locks into the receiving hole 29 of the left vertical rod 1b on the side end surface Q on the side opposite to the side end surface P on the side where the bearing hole 23 of the movable blade 4 is provided . Is provided. The locking shaft body 26 is detachably attached to a shaft holding hole 30 provided on the side end surface Q of the movable blade 4, and a coil spring 28 is inserted in the inner part of the shaft holding hole 30. As a result, the locking shaft body 26 appears and disappears by applying the biasing force of the coil spring 28. Therefore, when the movable wing 4 is pushed toward the left vertical shaft 1b, the locking shaft body 26 becomes the biasing force of the coil spring 28. The shaft 21 is retracted into the shaft holding hole 30 and the insertion portion 21 of the rotating shaft body 5 comes out of the bearing hole 23 so that the movable blade 4 can be removed. Further, the above-described locking shaft body 26 may be fixed without providing the coil spring 28 and without projecting or protruding the protruding length from the side end face Q.

  When the movable wing 4 and the left and right vertical rods 1a and 1b and the upper and lower rods 2 and 3 are made of different materials, generally, the left and right vertical rods 1a and 1b and the upper and lower rods 2 and 3 are made of relatively strong aluminum or While stainless steel or the like is used, it is assumed that a relatively low strength material such as wood or glass is applied to the movable blade 4. In addition to the fact that the left and right vertical rods 1a and 1b and the upper and lower rods 2 and 3 support the movable blade 4, the width of the left and right vertical rods 1a and 1b is formed as narrow as possible to improve the appearance. This is because it is assumed that the movable wing 4 is visually conspicuous by making it inconspicuous and a design effect of the product is obtained. The left and right vertical rods 1a and 1b and the vertical rods 2 and 3 have a minimum space S in which the transmission racks 7a and 7b and the coaxial gear 8 for rotating the movable blade 4 can be stored, and each movable blade 4 The material is not particularly limited as long as it has durability capable of withstanding the weight. The shape and size of the knob 9 may be, for example, a circular shape or a polygonal shape as long as the user can easily grasp it with a finger other than the square shape shown in the present embodiment.

FIG. 6 shows another embodiment of the movable louver of the present invention. Specifically, as shown in FIGS. 5A and 5B, the knob 31 slides to the left and right along the longitudinal direction of the lower rod 3, and the knob 31 further includes an operation interlocking rack 32 extending to the left and right. The operation interlocking rack 32 meshes with a start transmission spur gear 34 attached to the lower end of the vertical shaft 33, and a drive bevel gear 36a is attached to the upper end of the vertical shaft 33. They are engaged perpendicularly to a driven bevel gear 36b attached to one end of the horizontal shaft 35. A first reduction spur gear 37a is attached to the other end of the horizontal shaft 35. The first reduction spur gear 37a is a second reduction spur gear 37b having a small diameter, and then a third reduction spur gear 37c having a large diameter. The transmission horizontal shaft 38 that meshes with the small-diameter fourth reduction spur gear 37d alternately in the size and further rotates the fourth reduction spur gear 37d around the horizontal axis and meshes with the transmission racks 7a and 7b to move up and down. A final transmission spur gear 39 is attached. Even with the movable louver formed as described above, the operation when the user opens and closes all the movable wings 4 can be lightened in the same manner as the movable louver that operates the knob 31 up and down. Furthermore, although illustration is omitted, it is also possible to fit a cap with only the bearing hole 23 opened to the entire side end of the movable blade 4. In this way, the durability of the movable blade 4 when the insertion portion 21 of the rotating shaft 5 is inserted into the bearing hole 23 is further ensured.
