Description

shutter

The present invention relates to a shutter having a rectangular louver that can be tilted to adjust light, shadow, wind, visual field, sound, and the like.

As a means to adjust sunlight, shadow, wind, temperature, sound, and field of view in windows that are the most susceptible to environmental influences from outside to inside and from inside to outside, multiple 2. Description of the Related Art A louver shutter (shutter) is known as a fitting having a plate-like (rectangular) louver that is tiltable. This type of shutter is equipped with multiple louver tilt mechanisms, and by adjusting the angle of multiple louvers in synchronization by the tilt mechanism, sunlight, shadow, wind, temperature, sound, and visual field can be easily adjusted. Can be done.

In recent years, wooden shutters that use natural wood to enhance the appearance of the interior have attracted attention. A wooden shutter can be easily used as a fitting by providing a plurality of rectangular louvers on a frame such as an indoor door or partition, and a plurality of louvers can be attached to the frame constituting the door or partition. A tilting mechanism is housed. Since the wooden joinery is inferior in rigidity to the aluminum joinery, it is necessary to accommodate the louver tilting mechanism in the wooden frame while maintaining sufficient strength.

For this reason, a wooden movable louver has been proposed in which a plurality of louvers are provided with pinion gears and a mechanism that rotates the plurality of pinion gears simultaneously by operating the rack gears (see, for example, Patent Document 1). In the conventional wooden movable louver disclosed in Patent Document 1, a rack gear is reciprocated in the axial direction by rotating an operation pinion gear, and a plurality of louvers are simultaneously rotated by rotating pinion gears provided on the plurality of louvers. The tilt of the camera is adjusted in synchronization.

¡By configuring the tilting mechanism by combining the rack gear and pinion gear, it can be applied as a wooden joinery while maintaining strength.

However, the conventionally proposed wooden movable louver adjusts the inclination of a plurality of louvers by reciprocating the rack gear, so the interval between the pinion gears is determined by the shape and size of the teeth of the rack gear. End up. That is, the interval between the plurality of louvers is affected by the shape and size of the teeth of the rack gear. In other words, since the rack gear is a straight gear developed by developing a spur gear, the interval between the pinion gears depends on the tooth pitch, and the interval between the plurality of louvers is determined by the interval between the pinion gears determined by the rack gear. Become.

For this reason, it is difficult to arrange the pinion gears at equal intervals with high accuracy, and in order to arrange a plurality of louvers evenly with high accuracy (in order to arrange them aesthetically), the relationship between the louvers and the pinion gears It will be necessary to make adjustments. In addition, since it is difficult to obtain a cumulative system, it is very difficult to apply it without deteriorating the appearance, considering that it is applied as a long wooden shutter, such as a shutter with a length corresponding to a blow-through window. Met. That is, there is a problem that it is difficult to secure the shielding property.

That is, the sizes of the openings such as the windows are varied and the size of the shutter as the fitting is also varied, and a shutter having louvers with various intervals is required for the purpose of use. In order to apply a tilting mechanism consisting of a rack gear and a pinion gear to an louver with an arbitrary interval, it is necessary to arbitrarily adjust the shape and size of the teeth of the rack gear. It was not applicable to other shutters.

The above-mentioned problems are not limited to wooden, but also exist when applied as a tilting mechanism for metal or glass louvers.

JP 2007-23760 A

The present invention has been made in view of the above situation, and provides a shutter that can arrange louvers at a predetermined interval even when using a mechanism that synchronously tilts a plurality of louvers by a combination of a rack gear and a pinion gear.

As shown in FIG. 1, the shutter 11 according to the present embodiment includes a pair of wooden vertical frames (styles) 1 that are parallel to each other as a frame member, and wooden rails 2 that connect upper portions and lower portions of the styles, respectively. A wooden frame 3 is formed. Between the pair of styles 1, a plurality of natural wooden long plate-like wooden louvers 4 are provided at equal intervals in the vertical direction as louvers. The plurality of wooden louvers 4 are arranged in parallel to each other, and the end portions in the longitudinal direction are provided. Each is rotatably supported by the style 1.

The style 1 on one side (left side in FIG. 1: the other end side of the wooden louver 4) is provided with a rotation support portion 6 (details will be described later), and one end portion of the plurality of wooden louvers 4 is the rotation support portion 6. It is pivotally supported via the shaft. The style 1 on the other side (right side in FIG. 1: one end side of the wooden louver 4) is provided with an interlocking mechanism portion 8 (details will be described later), and the other end portion of the plurality of wooden louvers 4 is the interlocking mechanism portion 8. Is supported in a state of being rotated in conjunction with each other. Further, the interlocking mechanism unit 8 has a function of holding the rotation positions (tilting state) of the plurality of wooden louvers 4.

When the tilting operation of the wooden louver 4 is performed with the shutter 11 shown in FIG. 1, it is performed by pushing or pulling the upper or lower part of any wooden louver 4 by hand.

That is, as shown in FIG. 1 (a), by pulling the upper part of the wooden louver 4 or pushing the lower part from the closed state of the wooden louver 4, as shown in FIG. 1 (b), The upper part of the wooden louver 4 is tilted inward and the tilt position is maintained. In this state, for example, external light is taken in a state where the visual field from the outside is blocked.

Further, as shown in FIG. 1A, when the wooden louver 4 is closed, the wooden louver 4 is tilted horizontally by pulling the upper part of the wooden louver 4 or pushing the lower part. The horizontal state is maintained. In this state, for example, external light is taken in with a view to the outside secured.

Further, as shown in FIG. 1 (a), the upper portion of the wooden louver 4 can be operated by pulling the upper portion of the wooden louver 4 further from the closed state, as shown in FIG. 1 (c). Is tilted downward and the tilt position is maintained. In this state, for example, external light is sufficiently taken in with the external visual field blocked.

The configuration of the shutter 11 including the interlocking mechanism portion and the rotation support portion described above will be described in detail with reference to FIGS.

2 and 4, a vertical groove 5 is formed in the vertical direction on the inner edge of the style 1 on one side, and the vertical groove 5 accommodates a rotation support portion 6 extending in the vertical direction. A rectangular groove 7 is accommodated in the vertical direction on the inner edge of the style 1 on the other side, and an interlocking mechanism portion 8 extending in the vertical direction is accommodated in the rectangular groove 7.

The rotation support part 6 will be described.

As shown in FIGS. 2, 4, and 5, a long bush holder 15 having a U-shaped cross section is fitted in the longitudinal groove 5 of the style 1 (the other end side of the wooden louver 4) on one side, and the bush holder A plurality of holding holes 16 are formed in the vertical direction 15. The bush holder 15 is formed by connecting a plurality (two in the illustrated example) of bush holder pieces 15a with connectors (not shown).

A cylindrical bush 17 is fitted in each holding hole 16 at a position corresponding to the support interval of the wooden louver 4, and a pin 19 as a support pin urged to the protruding side by a compression coil spring 18 is fitted to the bush 17. Each is provided. A pin hole 20 is formed in the end portion (the other end side) of the wooden louver 4, and a pin 19 is fitted into the pin hole 20 in a biased state so that the end portion of the wooden louver 4 is rotatably supported. .

Bush holder 15, bush 17 and pin 19 are made of resin (plastic), for example, a molded product made by injection molding.

Since the pin 19 that supports the end portion of the wooden louver 4 is provided in the style 1 using the bush holder 15, it is possible to maintain the distance from the interlocking mechanism portion described later with high accuracy. That is, compared with the case where the pin 19 is directly provided on the style 1, the man-hour and time for drilling are not required, the manufacturing time can be shortened, and the manufacturing accuracy can be improved by eliminating the position error. .

The interlocking mechanism unit 8 will be described.

As shown in FIGS. 2, 3, 4, 6, and 7, a long plate-like bottom rail 21 is attached to the bottom of the rectangular groove 7 of the style 1 on the other side (one end side of the wooden louver 4). The bottom rail 21 is formed by connecting a plurality (two in the illustrated example) of bottom rail pieces 21 a with connectors 22. A long bottom rail 21 is arranged along the longitudinal direction of the rectangular groove 7.

The bottom rail 21 is covered with a long top cover 23 having a U-shaped cross section, and the bottom surface of the top cover 23 covers the opening of the rectangular groove 7. Similarly to the bottom rail 21, the top cover 23 is also formed by connecting a plurality (two in the illustrated example) of top cover pieces 23 a with connectors (not shown).

Rail grooves are formed at both ends in the width direction of the bottom rail 21, and rail grooves are formed at both ends in the width direction inside the bottom portion of the top cover 23. A long plate-like rack member 24 is supported so as to be reciprocally movable in the longitudinal direction across the rail groove of the bottom rail 21 and the rail groove of the top cover 23. The rack member 24 is formed by connecting a plurality (two in the illustrated example) of rack member pieces 24 a with connectors 22. That is, a rack member is obtained by dividing the plurality of rack member pieces 24a.

When the rack member pieces 24 a are connected by the connector 22, the long rack member 24 is arranged in the longitudinal direction of the bottom rail 21 and the top cover 23. The rack members 24 are arranged to be movable in opposition to each other, and a plurality of sets (a plurality of sets including the same number of louvers 4 as the number of louvers 4) of rack gears 25 are provided on the opposing surface of the rack member 24 (rack member piece 24a) in the longitudinal direction. Each is formed.

Since a plurality of bottom rail pieces 21a are connected by a connector 22 to form a bottom rail 21 having an elongated shape, a single bottom rail piece 21a with improved individual accuracy is connected to improve accuracy as a whole. A long bottom rail 21 is formed.

Similarly, since a plurality of rack member pieces 24a are connected by the connector 22 to form a long rack member 24, one rack member piece 24a that maintains the accuracy of the gear pitch of each rack gear 25 is maintained. As a whole, a long rack member 24 having a high accuracy in the positional relationship between the gear pitch and the rack gear 25 is configured. Similarly, since a plurality of rack members 24 are connected by connectors 22 to form a long part, one rack member 24 that maintains the accuracy of the gear pitch of each rack gear 25 is connected. As a whole, a long component having a high accuracy of the positional relationship between the gear pitch and the rack gear 25 is configured.

The pinion members 31 are arranged at equal intervals according to the upper and lower arrangement intervals of the wooden louvers 4, and the pinion members 31 are fitted into the support holes 32 at the end (one end side) of the wooden louvers 4. The pinion member 31 includes a pinion gear 33 and a pin cylinder 34 that are integrally provided, has a rotation center around the tilting axis of the wooden louver 4, and is accommodated in the style 1.

That is, as shown in FIG. 7, the set of rack gears 25 is configured with the number of teeth (for example, 7 teeth) necessary for tilting the wooden louver 4, and the pinion gear 33 is interposed between the sets of rack gears 25 of the pair of rack members 24. Are arranged in mesh with each other.

Since the set of rack gears 25 is configured with the number of teeth necessary for tilting the wooden louver 4, the arrangement interval of the wooden louvers 4 (the pinion gear 33 of the pinion gear 33) at a predetermined interval (pitch) regardless of the pitch of the tooth shape of the rack gear. Arrangement interval) can be set.

That is, in the case of a rack gear in which continuous teeth are formed, the arrangement interval of the wooden louvers 4 (the arrangement interval of the pinion gears 33) is determined by the shape and size of the teeth, and it is difficult to obtain the accumulated accuracy. A configuration in which one set of rack gears 25 is engaged with each other for each pinion gear 33, and an interval between adjacent sets of rack gears 25 is set to a predetermined interval, whereby an arrangement interval of the wooden louvers 4 (an arrangement interval of the pinion gears 33) is arbitrarily set. It becomes possible to set to a predetermined interval.

In particular, one rack member piece 24a that maintains the accuracy of the gear pitch and the like of each rack gear 25 is connected to form a long rack member 24 that has a high accuracy in the positional relationship between the gear pitch and the rack gear 25 as a whole. Therefore, even if it is a resin molded product, it is possible to maintain the accuracy of the arrangement interval of the pinion gear 33 with a very high accuracy and to accurately set the arrangement interval of the wooden louvers 4 to enhance the appearance.

Further, since the rack member piece 24a is a resin molded product, the rack gear 25 having uniform accuracy can be obtained, and the rack member 24 capable of maintaining high accuracy of the assembled product can be obtained at low cost. That is, for example, since the rack member piece 24a having the same accuracy can be formed by injection molding, it is possible to obtain the rack member 24 in which a certain accuracy is always maintained without variation in error.

In addition, although it was set as the structure which has arrange | positioned the pinion member 31 between a pair of rack members 24, the rack member 24 can also be provided only in one side. Even when the rack member 24 is provided only on one side, the set of rack gears 25 is configured with the number of teeth (for example, 7 teeth) necessary for the tilting of the wooden louver 4, and therefore, regardless of the pitch of the rack gear teeth shape. The arrangement interval of the wooden louvers 4 (the arrangement interval of the pinion gears 33) can be set at an arbitrary interval (pitch).

A rotation hole 35 is formed on the bottom surface of the top cover 23 so that the end surface of the pin cylinder 34 of the pinion member 31 faces, and two tilting pins 36 are provided on the end surface of the pin cylinder 34. Two support holes 32 are formed at the end (one end side) of the wooden louver 4 at a position corresponding to the pin hole 20, and the two tilt pins 36 of the pin cylinder 34 are fitted in the support hole 32. 2 and 7, the plurality of sets of rack gears 25 of the pair of rack members 24 are provided at intervals corresponding to the pinion members 31, that is, at the arrangement intervals of the wooden louvers 4, respectively. The rack gear 25 meshes with the pinion gear 33 of the pinion member 31.

Rack members 24 are provided on both sides of the pinion gear 33, and the pinion gear 33 is sandwiched between the pair of rack gears 25. Therefore, the rotation position of the pinion gear 33 is maintained, that is, the tilting position of the wooden louver 4 is maintained (the position where the hand is tilted and released) is maintained.

Further, since the pinion gear 33 is sandwiched between the rack gears 25 from both sides, even if an excessive rotational force is applied to any of the pinion gears 33, that is, an excessive tilting force is applied to any of the wooden louvers 4, the pinion gear 33 The meshing between the rack 33 and the rack gear 25 is reliably maintained. For this reason, only one wooden louver 4 does not have a different angle.

The bottom rail 21 and the top cover 23 are each made of resin, the rack member piece 24a of the rack member 24, and the plurality of sets of rack gears 25 are made of integral resin, and the pinion gear 33, pin cylinder 34, and tilting pin 36 of the pinion member 31 are made. Is made of an integral resin, for example, a molded product made by injection molding.

Since the rack member piece 24a, the rack gear 25, and the pinion member 31 of the rack member 24 are molded products of resin (plastic), it is possible to produce a highly accurate standard plastic component by injection molding so that the length can be increased. There is no limitation, and high-precision uniformity and synchronization required for the wooden shutter 11 are possible. That is, since the rack member piece 24a, the rack gear 25, and the pinion member 31 having the same accuracy can be formed, it is possible to obtain an assembly in which constant accuracy is always maintained without variation in error.

A set of rack gears 25 in the plurality of sets of rack gears 25 of the rack member pieces 24a of the rack member 24 is composed of, for example, seven teeth as shown in FIG. The interval between the teeth is set to a dimension (for example, 26 mm) equal to the vertical arrangement interval of the pinion member 31 (the vertical arrangement interval of the wooden louver 4). Since there is an appropriate interval between the pair of rack gears 25, a plurality of sets of rack gears 25 are produced at intervals equal to the upper and lower arrangement intervals of the wooden louvers 4 at intervals not depending on the gear pitch. Is possible.

Further, by arbitrarily setting the interval between the teeth of the center of a pair of adjacent rack gears 25, it is possible to deal with wooden louvers 4 of any kind of width. Further, by appropriately selecting a set of rack gears 25 to be used, a single rack member 24 can correspond to the wooden louvers 4 having a plurality of widths.

For example, in the example shown in FIG. 9A, the interval between the teeth of the center of a pair of adjacent rack gears 25 is set to 26 mm, for example, a width of 26 mm, a width of 52 mm, and a width of 78 mm. This can correspond to the wooden louver 4. Incidentally, when the rack gear 51 having the same tooth width is formed with continuous teeth, as shown in FIG. 9B, the vertical arrangement interval of the pinion members 31 (the vertical arrangement interval of the wooden louvers 4) depends on the gear pitch. Will be decided. In this case, the center of the tooth cannot be arranged at intervals of 26 mm, and accuracy in units of hundredths is required to approximate the interval of 26 mm, and it is very difficult to obtain cumulative accuracy.

In the plurality of sets of rack gears 25 of the rack member pieces 24a of the rack member 24, the interval between the teeth of the center of the adjacent pair of rack gears 25 is the vertical arrangement interval of the pinion members 31 (the vertical arrangement interval of the wooden louvers 4). Therefore, the wooden louvers 4 can be arranged at equal intervals and can be easily arranged at arbitrary intervals. Thereby, the several wooden louver 4 can be arrange | positioned at equal intervals, without deteriorating appearance.

The procedure for assembling the shutter 11 will be described.

The rotation support portion 6 has a bush holder 15 fitted in the longitudinal groove 5 of the style 1, and a bush 17, a compression coil spring 18, and a pin 19 are set in the holding hole 16. Since the bush holder 15 is used, there is no need to process a hole for inserting the bush 17 or the like into the wooden style 1. The upper end and the lower end of the vertical groove 5 of the style 1 are stopped by a stopper (not shown).

In the interlocking mechanism portion 8, after the bottom rail 21 and the top cover 23 are fitted together, a pair of rack members 24 are inserted in a state where a plurality of sets of rack gears 25 face each other. The position of the rack member 24 is adjusted to a predetermined position, the pinion member 31 is inserted through the rotation hole 35, and the pinion gears 33 are engaged with the plurality of opposing rack gears 25 (state of FIG. 3).

At this time, the tilting pins 36 of the pinion member 31 are all oriented in the same state. The interlocking mechanism portion 8 is fitted into the rectangular groove 7 of the style 1, and the upper end and the lower end of the rectangular groove 7 are stopped by a stopper (not shown). In this state, the rotation of the pinion member 31 causes the rack member 24 to reciprocate in opposite directions, and the moving end is restricted by the stop material.

The upper end portions and the lower end portions of the style 1 in which the rotation support portion 6 is fitted and the style 1 in which the interlocking mechanism portion 8 is fitted are connected by the rail 2 to form the frame 3. After the frame 3 is formed, the wooden louvers 4 are inserted one by one between the tilt pins 36 and 19 of the pinion member 31, and the tilt pins 36 are fitted into the support holes 32 and the pins 19 are inserted into the pin holes 20. Mating.

That is, after the tilting pin 36 is fitted into the support hole 32 on one end side of the wooden louver 4, the other end side of the wooden louver 4 is moved in a state where the pin 19 is moved against the urging force of the compression coil spring 18. The pin hole 20 is aligned with the position of the pin 19 and the pin 19 is fitted into the pin hole 20 by the urging force of the compression coil spring 18. By attaching all the wooden louvers 4, the shutter 11 is obtained.

Thereby, by arranging the other end side of the wooden louver 4 in a state in which the pin 19 is moved against the urging force of the compression coil spring 18, the assembly can be easily performed, and the number of assembling steps can be reduced. Is possible and does not require skill in assembly.

In the shutter 11 described above, the other end of the wooden louver 4 is supported by the resin bush 17, the compression coil spring 18, and the resin pin 19, so that even when the wooden louver 4 needs to be replaced separately. It can be easily replaced.

The replacement of the wooden louver 4 will be described with reference to FIG. FIG. 10A shows the situation on the rotation support part side, and FIG. 10B shows the situation on the interlocking mechanism part side.

As shown in FIG. 10A, the support on the other end side of the wooden louver 4 is released by cutting the resin pin 19 that supports the other end side of the wooden louver 4 to be replaced. The wooden louver 4 is removed from the frame 3 by moving the other end of the wooden louver 4 to the outside of the frame 3 and removing one end of the wooden louver 4. At this time, as shown in FIG. 10B, the tilt pin 36 of the pinion member 31 faces the inside of the frame 3.

The cut pin 19 is removed, a new pin 19 is mounted on the bush 17, and a new wooden louver 4 is inserted between the tilt pin 36 and the pin 19 of the pinion member 31 and tilted into the support hole 32 (see FIG. 6). The pin 36 is fitted and the pin 19 is fitted into the pin hole 20 (see FIG. 5).

Thus, the wooden louver 4 can be replaced easily and in a short time. In other words, for example, in a shutter in which all louvers are provided with one operating arm for interlocking, when replacing one louver, the operation arm related to all louvers and the louver that needs to be replaced It was necessary to separate and install the device, which was a large-scale work and required a lot of labor. On the other hand, in the shutter 11 of the present invention, since the interlocking mechanism portion 8 is not directly related between the wooden louvers 4, one wooden louver 4 can be easily replaced in a short time.

The open / close state of the wooden louver 4 in the shutter 11 described above will be described with reference to FIGS.

The state shown in FIG. 1 (a) is a state in which the wooden louver 4 is closed. As shown in FIG. 8 (a), one (left side in the figure) of the rack member 24 is positioned at the top and the other ( The rack member 24 on the right side in the drawing is located at the lowest level. At this time, the teeth located on the lower side of one (left side in the figure) of the rack gear 25 and the teeth located on the upper side of the other (right side in the figure) of the rack gear 25 are engaged with the pinion gear 33.

The state shown in FIG. 1B is a state in which the upper part of the wooden louver 4 is tilted inward, and the wooden louver 4 can be operated by pulling or pushing the upper part of any wooden louver 4. The upper part of the camera is tilted inward to maintain the tilt position. That is, as shown in FIG. 8B, by tilting one of the wooden louvers 4, one rack member 24 (left side in the figure) moves downward from the uppermost stage via the pinion gear 33 and at the same time the other ( The rack member 24 on the right side in the figure is moved upward from the lowermost stage, all the pinion gears 33 are rotated counterclockwise, and all the wooden louvers 4 are tilted at the same angle, so that the tilt position is maintained.

When the wooden louver 4 is tilted horizontally, the wooden louver 4 is tilted horizontally to maintain the horizontal state by pulling the upper part of any wooden louver 4 or pushing the lower part. It will be in the state. That is, as shown in FIG. 8 (c), by tilting one of the wooden louvers 4, one (left side in the figure) rack member 24 moves downward via the pinion gear 33 and at the same time the other (right side in the figure). ) Of the rack gear 24 moves upward, and all the pinion gears 33 rotate counterclockwise, and the teeth located at the center of one (left side in the figure) of the rack gear 25 and the rack gear 25 on the other side (right side in the figure). The teeth located at the center of the gear mesh with the pinion gear 33. Thereby, all the wooden louvers 4 tilt at the same angle, and a horizontal position is hold | maintained.

The state shown in FIG. 1 (c) is a state in which the upper part of the wooden louver 4 is inclined downward, and the upper part of the wooden louver 4 is lowered by pulling the upper part of one of the wooden louvers 4 downward. And the tilt position is maintained. That is, as shown in FIG. 8 (d), by tilting one of the wooden louvers 4, one (left side in the figure) rack member 24 moves further downward via the pinion gear 33 and at the same time the other (in the figure). The right side rack member 24 is further moved upward, all the pinion gears 33 are rotated counterclockwise, and all the wooden louvers 4 are tilted at the same angle to hold the tilting position.

In the shutter 11 described above, the pinion gear 33 is rotated by tilting one of the wooden louvers 4, the rack member 24 is moved in the axial direction via the rack gear 25, and the pinion gear 33 is rotated via the other rack gear 25. By doing so, the plurality of wooden louvers 4 tilt in unison synchronously.

Since the rack piece 24a of the rack member 24 is provided with a pair of rack gears 25 at intervals corresponding to the pinion gears 33, the pinion gears 33 can be arranged at intervals not depending on the pitch of the gears. 4 can be arranged at predetermined intervals. Further, by changing the rack gear 25 to be used, the width of the plurality of wooden louvers 4 can be accommodated by one rack member 24.

Since the rack member 24 is configured by dividing the rack piece 24a, the rack gear 25 to be used can be adjusted by changing the connection state of the rack piece 24a, and the louver 4 having various widths is provided. The shutter 11 can be used correspondingly.

As a result, the wooden louvers 4 can be arranged at a predetermined interval even if a mechanism for tilting the plurality of wooden louvers 4 in synchronization with the combination of the rack gear 25 and the pinion gear 33 is used. In other words, regardless of the length of the shutter 11 and the width of the wooden louver 4, the appearance can be improved while maintaining high functionality.

For example, even when applied to a length of about 6 m corresponding to the second-floor blow-through window, the wooden louvers 4 are uniformly arranged, and the wooden louvers 4 are surely synchronized with the shutter 11. By using the wooden frame including the frame 3, it can be used as a wooden shutter and can be applied as a wooden fitting.

Further, since the pinion gear 33 is sandwiched between the pair of rack gears 25, a resistance force for maintaining the tilt angle is obtained when any one of the wooden louvers 4 is operated, and it is easy to tilt to an arbitrary angle. Even if an excessive load is applied only to one of the wooden louvers 4, the engagement between the pinion gear 33 and the rack gear 25 is reliably maintained, and only the wooden louver 4 having an excessive load is not at a different angle. . For this reason, the operability of the wooden louver 4 is improved, and it is possible to reliably suppress a decrease in appearance.

In other words, there is no need for an operating bar or the like for synchronizing the tilting movement of the wooden louver 4, and the appearance is such that the plurality of wooden louvers 4 are only supported by the frame 3, and the design as a wooden fitting is kept high. It becomes possible to make the shutter 11 with high operability, and it is possible to sufficiently cope with conflicting demands such as a demand for appearance and a demand for high functionality.

In addition, since any wooden louver 4 does not have a different angle, in combination with a configuration in which an operation rod for synchronization does not exist, for example, even when the shutter 11 is applied to a sliding door, the sliding operation is performed. At this time, the wooden louver 4 does not interfere with the frame 3 on the other side, and the operation function is not impaired.

Further, by releasing the support of the other end of the desired wooden louver 4 by cutting the resin pin 19 or the like, only the necessary wooden louver 4 can be removed from the frame 3, and the wooden louver 4 can be replaced. And maintenance can be performed easily. By arranging the other end of the wooden louver 4 in a state where the pin 19 is moved against the urging force even at the time of initial assembly, the pin 19 is fitted to the wooden louver 4 by the urging force and assembled. Man-hours can be reduced, and skill required for assembly is not required.

Further, since the rack member 24 and the like provided with the pinion gear 33 and the rack gear 25 are made of resin, the parts can be manufactured by injection molding, and high-precision parts can be obtained at low cost. That is, the pinion gear 33 and the rack gear 25 having uniform accuracy can be obtained, the accuracy of the assembled product can be maintained high, and a product with high accuracy can be obtained at low cost.

Also, since it is resinous, it is lightweight and has excellent self-lubricating properties, so a special lubricant is not required and a clean mechanism can be achieved. Furthermore, since the entire rack member 24 including the rack gear 25 is made of resin, it becomes possible to manufacture a fixed-size molded product with high accuracy and low cost regardless of the length. By increasing the tooth widths of the pinion gear 33 and the rack gear 25, the wear resistance and mechanical strength are improved, and the service life can be extended.

Therefore, in the shutter 11 described above, the wooden louvers 4 can be arranged at a predetermined interval even if a mechanism in which a plurality of wooden louvers 4 are tilted synchronously by a combination of the rack gear 25 and the pinion gear 33 is used. Regardless of the number of arrangements, that is, regardless of the length of the shutter 11 and the width of the wooden louver 4, it is possible to improve the appearance while maintaining high functionality.

In the shutter 11 having the above-described configuration, step portions on the opposite sides of the front and back sides are mainly formed at both ends in the width direction of the wooden louver 4 as shown in FIG. Since the step portion is formed in the wooden louver 4, the step portions are fitted with each other in a state where the wooden louver 4 is closed as shown in FIGS. 1 (a), 2, and 8 (a). Thus, a large number of wooden louvers 4 are brought into a flush state. For this reason, when the wooden louver 4 is closed, there is no light leakage, and at the same time, the appearance is remarkably improved.

The assembly procedure of the shutter 51 described above will be described. The following procedure is described assuming that the shutter 51 is assembled according to an order, for example.

* Depending on the size of the order, cut the wood 1, style 1, rail 2 and frame 3. A pin hole 20 is made in the end face of the wooden louver 4, and a rotation hole 35 is made in the top cover 57 to which the top cover piece 57a is connected using a jig at intervals according to the order size. In addition, the holding holes 16 are formed in the bush holder 54 to which the bush holder pieces 54a are connected, using a jig at intervals according to the order size.

The bottom rail piece 55a is connected by the connector 56 and the rack member piece 58a is connected by the connector 59, and the bottom rail 55 and the rack member 58 that are the connecting members are connected to a predetermined length according to the dimensions of the mechanism portion determined by the order size. Cut it up. The top cover 57 is fitted into the bottom rail 55 connected by the connector 56, and the rack member 58 serving as a connecting member is inserted into a case made up of the bottom rail 55 and the top cover 57 from the end portion at a predetermined position.

スタイル Paint the wooden parts Style 1, Rail 2, Frame 3 and Wooden Louver 4 for each part. A case composed of a bottom rail 55 and a top cover 57 is fitted into the rectangular groove 7 of the style 1 on the right side in FIG. 11, and a long bush holder 54 composed of a bush holder piece 54a connected by a connector is placed on the left side in FIG. Fit into the style 1 longitudinal groove 5.

The style 1 arranged on both sides and the rail 2 arranged on the upper and lower sides (only the upper part is shown in FIG. 11) are coupled using screws, dowels, adhesives and the like. It is confirmed that the rack gear 25 of the rack member 58 (rack member piece 58a) is in an appropriate position from the rotation hole 35 formed in the top cover 57, the pinion member 31 is inserted from the rotation hole 35, and a pair of rack gears are inserted. 25, the pinion gear 33 of the pinion member 31 is engaged.

The bush 17 is inserted into the holding hole 16 of the bush holder 54, and the compression coil spring 18 and the pin 19 are inserted into the bush 17. A hole drilled in the end face of the painted wooden louver 4 is inserted into the tilting pin 36 of the pinion member 31 obliquely from the front, and the wooden louver 4 is leveled with the pin 19 pushed into the bush 17. The pin 19 is inserted into the pin hole 20 of the wooden louver 4 by the spring force of the compression coil spring 18 in a state where the positions of the pin 19 and the pin hole 20 coincide.

Thereby, the wooden louver 4 is supported so as to be rotatable over the pinion member 31 and the pin 19, that is, over the pair of styles 1. Finally, the hole drilled when connecting the style 1 and the rail 2 is covered with a wooden plug to complete.

Since the shutter 51 described above supports the wooden louver 4 by fitting the case made of the bush holder 54, the bottom rail 55 and the top cover 57 to the wooden style 1, the supporting hole and the like are processed in the style 1. There is no need to do. Further, the wooden louvers 4 having various widths can be dealt with by changing the interval of the holes in the bush holder 54 and the top cover 57.

In addition, in the shutter that supports the wooden louver by directly processing the support holes in the style (port), the finished product will be painted, so there is a gap between the wooden louver and the vertical / horizontal rail. On the other hand, it is necessary to perform the painting while tilting the wooden louver, and in order to maintain the appearance by eliminating the unevenness of painting, skilled painting techniques are required.

On the other hand, in the shutter 51 described above, the wooden louver 4 can be inserted and assembled after connecting the style 1 and the rail 2, so that the painted parts can be assembled, and it does not require a skillful technique. Can be improved.

Furthermore, since the shutter 51 described above has a structure in which the wooden louver 4 is fitted later, only the relevant part is replaced even if one wooden louver 4 is damaged or a failure occurs in the support portion. Can do. Since assembly and replacement are facilitated and painting after assembly is no longer necessary, an operator who requires skill in assembling, maintaining and inspecting the shutter 51 is not required.

In the above-described embodiment, the

shutters

11 and 51 including a plurality of wooden louvers 4 in a horizontal state have been described as examples. However, a shutter including a plurality of wooden louvers 4 in a vertical state may be used. Further, the shutter is not limited to the shutter 11 in which the louver and the frame body are made of wood, but it is possible to use a shutter in which the louver and the frame body are made of other materials such as resin, glass and metal.

とする By making the louver out of resin, it can be made into a louver with good processability and mass production. Further, by using the same resin as the pinion gear 33 and the supporting pin 19, intervening parts such as the tilting pin 36 and the bush 17 can be omitted. In some cases, the pinion gear 33 and the support pin 19 can be formed integrally with the louver. Further, the louver can be made of metal. For example, by using aluminum, it is possible to make the louver lightweight, rigid and difficult to rust.

In the above-described shutter 51, the connector 54b for connecting the bush holder piece 54a, the connector 56 for connecting the bottom rail piece 55a, the connector 57b for connecting the top cover piece 57a, and the connector 59 for connecting the rack member piece 58a are provided. Although each provided, the

connectors

56, 59, 57b, 54b can be all the same shape connectors (for example, the same connector as the connector 56). By using the same shape connector (same member), when the distance between the wooden louvers 4 is changed, the distance between the holding hole 16, the rack gear 25, and the rotation hole 35 is changed at the same time using the same parts. can do.

The shutters are not limited to wooden interior fittings, but can be applied, for example, as windows with glass louvers, ventilation opening / closing members, passage partitions, vehicles and public facilities. It can be applied as any other shutter functional member regardless of the interior or exterior, such as partitioning or partitioning in an office.

Even if the shutter of the present invention having the above-described configuration uses a mechanism in which a plurality of wooden louvers 4 are tilted synchronously by the combination of the rack gear 25 and the pinion gear 33, the wooden louvers 4 are independent of the size and the arrangement interval of the wooden louvers 4. Can be arranged at a predetermined interval, particularly when the wooden louver 4 is closed, no gap is generated, and the shielding property is not deteriorated. Thereby, it is possible to reliably prevent light leakage and direct sunlight from entering, and to reliably block the influence of the environment of the inside and outside air, thereby improving the cooling / heating efficiency and contributing to the energy saving effect.

The present invention can be used in the industrial field of a shutter in which a rectangular louver for adjusting light, shadow, wind, visual field, sound and the like is tiltably provided.
