Description

  The present invention relates to an assembly of a movable louver rotating mechanism in which a rectangular movable louver for adjusting light, shadow, wind, visual field, sound, and the like is rotatably provided, and a movable louver fitting having a rotating mechanism. .

  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 A movable louver joinery is known as a joinery in which a shank-like (rectangular) movable louver is rotatably provided. This type of movable louver joinery is equipped with a movable louver rotation mechanism, and by adjusting the angle of a plurality of movable louvers in synchronization by the rotation mechanism, sunlight, shadow, wind, temperature, sound, visual field Can be easily adjusted.

In recent years, movable louver joinery that uses natural wood to enhance its appearance as an interior has attracted attention. A movable louver fitting can be used as a fitting by providing a plurality of rectangular movable louvers on a frame such as an indoor door or partition, and a plurality of movable louvers can be attached to the frame constituting the door or partition. A rotating mechanism is accommodated. Movable louver joinery with an opening in the wooden movable louver part is inferior in rigidity compared to a flat door (flash door) whose surface is covered with a plate, so the movable louver rotating mechanism is maintained with sufficient strength. It must be housed in a frame.
For this reason, there has been proposed a movable louver using a mechanism in which a plurality of movable louvers are provided with pinion gears and the rack gears are operated to rotate the plurality of pinion gears simultaneously (for example, see Patent Document 1). In the conventional movable louver disclosed in Patent Document 1, the rack gear is reciprocated in the axial direction by rotating the operation pinion gear, and the pinion gears provided on the plurality of movable louvers are simultaneously rotated to move the plurality of movable gears. The louver tilt is adjusted in synchronization.
Such a combination of a rack gear and a pinion gear constitutes a turning mechanism, so that it can be applied as a joinery with strength maintained.

  However, the conventionally proposed movable louver adjusts the inclination of the plurality of movable louvers by reciprocating the rack gear, so the interval between the pinion gears is determined by the shape and size of the rack gear teeth. End up. That is, the interval between the plurality of movable 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 movable 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 movable louvers evenly with high accuracy (in order to arrange them in a good-looking manner), It will be necessary to adjust the relationship. In addition, since it is difficult to obtain the cumulative accuracy, for example, when considering application as a long movable louver fitting such as a movable louver fitting having a length corresponding to the blow-through window, it is possible to apply without reducing the appearance. It was very difficult. That is, there is a problem that it is difficult to secure the shielding property.

That is, the size of movable louver fittings having various sizes of openings such as windows has been diversified, and there is a demand for fittings having movable louvers at various intervals for the purpose of use. In order to apply a rotating mechanism consisting of a rack gear and a pinion gear to a movable louver at 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 joinery with louvers.
The above-described problem is not limited to wooden, and similarly exists when applied as a rotating mechanism for a movable louver made of metal or glass.

The rack member 24 to which the rack member piece 24a is connected has a tensile force in the longitudinal direction of the rack member 24 that is strengthened by fitting the circular protrusion 24c into the circular hole 24e, and the rack member piece 24a is not detached. As described above, the rail groove 26b (FIG. 9) is formed at both ends in the width direction inside the bottom portion of the top cover 23, and the rack member 24 is fitted between the rail grooves 26a and 26b. Movement in the direction in which the member piece 24a is removed is restricted. Thus, Bo Tomureru pieces 21a, by the top cover piece 23a and the rack piece 24a is connected, the rack member 24 of the elongated are arranged in the longitudinal direction of the bottom rail 21 and the top cover 23.
In this embodiment, with respect to the length in the extending (longitudinal) direction of the vertical frame 1, the main body portion (the portion excluding the protruding piece 24b) of the rack member piece 24a is the main body portion (connecting piece 21b) of the bottom rail piece 21a. The length is the same as that of the portion excluding.
The pair of rack members 24 are movably disposed opposite to each other, and the teeth of the rack gear 25 that mesh with the teeth of the pinion gear 33 are located at the intermediate position of the opposite surface of each rack member piece 24a on the side where the pinion gear 33 is disposed. Are formed in the longitudinal direction (FIG. 10).
Such bottom rail pieces 21a, by assembling the one pair of rack piece 24a of each of the top cover piece 23a and the pinion gear 33 as an assembly, one unit of those members is formed. By increasing the accuracy of these individual members, the long bottom rail 21, the top cover 23, and the rack member 24 having high accuracy as a whole are configured.

The pinion members 31 are arranged at equal intervals according to the upper and lower arrangement intervals of the movable louver 4, and the pinion members 31 are connected to the support holes 32 at the end (one end side) of the movable louver 4. The pinion member 31 is integrally provided with a pinion gear 33 and a pin tube 34 as a shaft portion at one end of the pinion gear 33, and has a rotation center around the rotation axis of the movable louver 4 and is accommodated in the vertical frame 1. It is like that.
That is, as shown in FIG. 10, one rack gear 25 is configured with the number of teeth (for example, 7 teeth) necessary for the rotation of the movable louver 4, and the pinion gear 33 is interposed between each pair 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 the rotation of the movable louver 4, the arrangement interval (pinion gear 33) of the movable louvers 4 at a predetermined interval (pitch) irrespective of the pitch of the tooth shape of the rack gear. Can be set.

That is, in the case of a rack gear formed with continuous teeth, the arrangement interval of the movable 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. An arrangement interval of the movable louvers 4 (an arrangement interval of the pinion gears 33) can be arbitrarily set by setting a configuration in which one set of rack gears 25 is engaged with each other for each pinion gear 33 and setting an interval between adjacent rack gears 25 to a predetermined interval. It becomes possible to set to a predetermined interval.
Although the pinion member 31 is arranged between the pair of rack members 24, the rack member 24 can be provided only on one side of the side surface 23 c of the top cover 23. 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 rotation of the movable louver 4, and therefore, regardless of the rack-shaped tooth shape pitch. Instead, the arrangement interval of the movable louvers 4 (the arrangement interval of the pinion gears 33) can be set at an arbitrary interval (pitch).
In addition, when the rack member is integrally formed and a single member is used, the pitch interval between the pinion gear and the rack gear does not exist, and the smoothness is lost when the movable louver is rotated. However, as in the present invention, the rack member pieces 24a connected and used have the same pitch between the rack gear 25 and the pinion gear 33, so that the movable louver 4 can be operated smoothly when rotated. Become.

  A through 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 rotation 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 movable louver 4 at a position corresponding to the pin hole 20, and the two rotation pins 36 of the pin cylinder 34 are fitted in the support hole 32. . As shown in FIGS. 3 and 10, the plurality of rack gears 25 of the pair of rack members 24 are provided at intervals corresponding to the pinion members 31, that is, corresponding to the arrangement intervals of the movable louvers 4. One rack gear 25 of the member piece 24 a meshes with the pinion gear 33 of one 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. For this reason, the engagement of the pinion gear 33 and the rack gear 25 becomes an appropriate resistance, and the rotation angle of the pinion gear 33 is maintained. That is, the position where the movable louver 4 is rotated and released is maintained at the rotation angle of the movable louver 4.
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 rack gear 25 are each made of integral resin, and the pinion gear 33, pin cylinder 34, and rotation pin 36 of the pinion member 31 are They are made of an integral resin, and are, for example, molded products produced by injection molding or compression molding.

  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 movable louver 4). Since an appropriate interval exists 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 movable louvers 4 at intervals not depending on the gear pitch. Is possible.

Further, by arbitrarily setting the interval between the central teeth of a pair of adjacent rack gears 25, it is possible to correspond to the movable louver 4 having any type of width. In addition, by appropriately selecting a set of rack gears 25 to be used, one rack member 24 can correspond to the movable louvers 4 having a plurality of widths.
For example, in the example shown in FIG. 12A, the distance between the teeth of the center of a pair of adjacent rack gears 25 is set to 26 mm, for example, the width of 26 mm, the width of 52 mm, and the width of 78 mm. It is possible to correspond to the movable louver 4.

With reference to FIGS. 1 and 14, the louver fitting 11 is provided with two guide grooves 70 in the upper frame 100 a of the mounting frame 100, and two louver fittings 11 are arranged in each guide groove 70. ing. The guide groove 70 has a concave cross-sectional shape that is recessed upward, and is fitted into the upper end portion of the horizontal frame 2 so as to protrude upward. In addition, although illustration is abbreviate | omitted, the lower part of the louver joinery 11 is also guided by the guide part of the attachment frame 100, and the louver joinery 11 is a structure which can be slid as a sliding door in the horizontal direction.
As described above, the rack member 24 of the louver fitting 11 has a plurality of rack member pieces 24a connected to each other. Of the pair of rack members 24, a lower end portion of a stopper pin 72 made of a hard material, for example, metal, is connected to a piece of the rack member 24 a that is connected to the uppermost position of the one rack member 24. The stopper pin 72 has a cylindrical shape, and is erected directly upward from the upper end portion of the rack member 24 with the shaft directed in the vertical direction.

At the position where the mounting frame 100 is closed by the louver fitting 11 (see FIG. 1A: closed state of the window frame), and the upper frame 100a at a position corresponding to the position directly above the position of the stopper pin 72, A stopper hole 73 having a circular cross section is formed upward from the lower surface of the upper frame 100a. Of the pair of rack members 24 that mesh with the pinion gear 33, only one rack member 24 is provided with the stopper pin 72, and the stopper pin 72 is not connected to the upper end portion of the other rack member 24.
In the state shown in FIG. 14A, the movable louver 4 is in the closed position (the movable louver 4 faces in the vertical direction), and the pair of rack members 24 that move up and down are at the same height position (this height is the middle). In this state, the upper end of the stopper pin 72 slightly exceeds the upper surface of the horizontal frame 2 and is positioned below the bottom surface of the upper frame 100a.
When the movable louver 4 moves from the closed position to the open position, the movable louver 4 faces in the horizontal direction, and the pinion gear 33 coupled to the movable louver 4 rotates in conjunction with the movable louver 4. Then, as shown in FIG. 14B, the rack gear 25 (see FIG. 10) meshed with the pinion gear 33 raises one rack member 24 having the stopper pin 72, and the other one not having the stopper pin 72. The rack member 24 is lowered. As one rack member 24 is raised, the stopper pin 72 is inserted into the stopper hole 73 formed immediately above. As described above, the stopper pin 72 is inserted into the stopper hole 73, whereby the louver joinery 11 is prevented from sliding in the lateral direction.
When the movable louver 4 is returned to the closed position again, the pinion gear 33 rotates in the opposite direction, and the one rack member 24 is positioned at the intermediate (initial) position shown in FIG.

As shown in FIGS. 15 and 16, a rotation adjustment mechanism 90 for the movable louver 4 (pinion gear) is provided on one side of the vertical frame 1. The rotational movement adjusting mechanism 90 is made to function when it is desired to fix the rotational angle of the movable louver 4.
The rotation adjustment mechanism 90 forms an extension part 31b in which a shaft part 31a on the other end side of an arbitrary pinion member 31 is extended. The extension part 31b penetrates the support hole 21a of the bottom rail and extends into the vertical frame 1. It extends from the bottom of the rectangular groove 7 to the inside of the vertical frame 1.
A clamping member 91 is provided inside the vertical frame 1. The clamping member 91 is provided with a pair of clamping plates 92 a and 92 b having a substantially parallel gap 95, and is connected by a base end portion 93 of the clamping plates 92 a and 92 b. Has been. An insertion hole 94a is formed in one clamping plate 92a, and a screw hole 94b is formed in the other clamping plate 92b. These holes 94a and 94b are formed in a direction perpendicular to the direction in which the gap 95 is formed. ing. A large-diameter hole 94c is formed in the base end portion 93 described above, and a shaft hole 94d is formed on the slightly large-diameter hole 94c side between the distal ends of the sandwiching plates 92a and 92b and the large-diameter hole 94c. The tip of the extension part 31b of the pinion member 31 is inserted through the shaft hole 94d.

The shaft 97 of the adjustment bolt 96 is inserted through the insertion hole 94a and the screw hole 94b. No thread is formed in the insertion hole 94a, and the shaft 97 is screwed into the screw hole 94b. A sleeve 98 is disposed on the shaft 97 of the adjustment bolt 96, and the diameter of the sleeve 98 is larger than the diameter of the insertion hole 94a, and is disposed between the head 99 of the adjustment bolt 96 and the clamping plate 92a. A slit 99a is formed in the head 99, and the width of the slit 99a is formed to a thickness that allows a coin to enter, and the adjustment bolt 96 can be rotated by the coin.
When the adjustment bolt 96 is rotated in the tightening direction, the sleeve 98 presses the holding plate 92a, the gap 95 is narrowed, and the shaft hole 94d strongly holds the extension 31b of the adjustment bolt 93. Therefore, the rotation of the pinion gear 33 is prevented. Since each pinion gear 33 is interlocked with the rack member 24, it is possible to prevent the rotation of all the pinion gears 33 interlocked with the rack member 24 by suppressing the movement of one pinion gear 33. As a result, the movable louver 14 rotation can be suppressed. In this way, by suppressing the rotation of the movable louver 14, the inclination angle of the movable louver 14 is changed due to the strong louver 14 being touched by a strong wind or a mischief of a child on a windy day. Can be prevented.

Next, a first assembly procedure of the movable louver rotating mechanism of the louver joinery 11 will be described.
This assembly procedure is a procedure for assembling the top cover piece 23a, the bottom rail piece 21a, the pinion member 31, and the rack member piece 24a as one unit.
Referring to FIGS. 6, 9, and 17, the top cover piece 23a is assembled to the bottom rail piece 21a. That is, the protrusion 21g formed on the bottom rail piece 21a is fitted into the stop hole 23d formed on the side surface 23c of the top cover piece 23a. Thereby, the rectangular cylinder by the top cover piece 23a and the bottom rail piece 21a is completed. When the top cover 23 is assembled to the bottom rail 21, rail grooves 26a and 26b (FIG. 9) are formed in the bottom rail 21, so that the rack member 24 is inserted between the pair of rail grooves 26a and 26b. Can do.

6, by inserting the pinion member 31 from the through hole 35, the pin cylinder 34 of the pinion member 31 is supported by the through hole 35, and the shaft portion 31a which is the other end of the pinion member 31 is the bottom. It is supported by the support hole 21f of the rail piece 21a. Thus, the assembly 13 of the top cover piece 23a, the bottom rail piece 21a, the pinion member 31, and the rack member 24 is assembled as one unit.
The assembly 13, 13 is assembled by connecting the plurality of bottom rail pieces 21a by fitting the circular protrusions 21 of the bottom rail pieces 21a into the circular holes 21e of the other adjacent bottom rail pieces 21a. Further, the assemblies 13 and 13 are assembled by fitting the circular protrusion 24c of the rack member piece 24a into the circular hole 24e of the other adjacent rack member piece 24a.
In addition, when the circular protrusion 21 of the bottom rail piece 21a is fitted into the circular hole 21e of the bottom rail piece 21a, the work can be performed from the outside of these members, but the assembly of the rack member pieces 24a is performed by these members. Therefore, if the rack member piece 24a is attached outside in advance and then assembled into the rail grooves 26a, 26b, it can be easily assembled.
Thus, by handling the top cover piece 23a, the bottom rail piece 21a, the pinion member 31, and the rack member piece 24a as one unit as the assembly 13, there is an advantage that the unit can be handled in units of assembly, repair, and sales. .
After the bottom rail piece 21 and the top cover 23 are assembled, the bottom rail piece 21 is assembled in close contact with the bottom of the rectangular groove 7 of the vertical frame 1 as shown in FIG. It does not come out of the hole 21e. Further, since the rack member 24 is assembled in the rail grooves 26a and 26b, the circular protrusion 24c of the rack member piece 24a does not come out of the circular hole 24e.

As described above, no fixing tool such as an adhesive is used for the attachment of the top cover piece 23a, the bottom rail piece 21a, the pinion member 31 and the rack member piece 24a, and the assembly of the assemblies 13, 13. About the removal of those members, it can decompose | disassemble into an individual component with the reverse procedure of the above-mentioned.
However, although the constituent members of the assembly 13 are detachable, for example, it is possible to fix the top cover piece 23a and the bottom rail piece 21a.
In addition, the pinion member 31 is inserted into the cylinder formed by the top cover piece 23a and the bottom rail piece 21a from the outside by making the maximum diameter of the pinion member 31 substantially the same as the inner diameter of the through hole 35. However, with respect to the shaft portion of the pinion member 31 on the through hole 35 side, the body portion (portion not supported by the through hole) is made larger than the through hole 35 so that the pinion member 31 cannot be removed from the through hole 35. Also good. In this case, it is necessary to perform the pinion member 31 simultaneously with the incorporation of the top cover piece 23a and the bottom rail piece 21a.

In the rotation support portion 6, the bush holder 15 is fitted into the concave groove 5 of the vertical frame 1, and the bush 17, the compression coil spring 18, and the 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 vertical frame 1. The upper and lower ends of the concave groove 5 of the vertical frame 1 are stopped by a stopper (not shown) (or by bringing the stopper pin 72 into contact with the bottom of the stopper hole 73: see FIG. 14).
The frame 3 is formed by connecting the upper and lower ends of the vertical frame 1 fitted with the rotation support portion 6 and the vertical frame 1 fitted with the connecting and assembling mechanism portion 8 with the horizontal frame 2. After the frame 3 is formed, the movable louvers 4 are inserted one by one between the rotation pins 36 and 19 of the pinion member 31, and the rotation pins 36 are fitted into the support holes 32 and are inserted into the pin holes 20. The pin 19 is fitted.

That is, after the rotation pin 36 is fitted in the support hole 32 on one end side of the movable louver 4, the other end side of the movable 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 made to match 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 movable louvers 4, the louver joinery 11 is completed.
As described above, by disposing the other end side of the movable louver 4 in a state where 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 louver fitting 11 described above, the other end side of the movable louver 4 is supported by the bush 17, the compression coil spring 18, and the pin 19, so that the movable louver 4 can be easily replaced even when it is necessary to replace it alone. Is possible.

Next, the example of the 2nd assembly procedure of the rotation mechanism of the movable louver of the louver fitting 11 mentioned above is demonstrated.
First, in order to form the bottom rail 21 to a length to be used, a plurality of bottom rail pieces are formed by fitting the circular protrusions 21 of the bottom rail piece 21a into the circular holes 21e of the other adjacent bottom rail pieces 21a. 21a is connected.
Further, in order to form the rack member 24 to a length to be used, a plurality of rack member pieces are obtained by fitting the circular protrusions 24c of the rack member piece 24a into the circular holes 24e of the other adjacent rack member pieces 24a. 24a is connected to an arbitrary length.
When the bottom rail 21 is completed, the protrusion 21g formed on the bottom rail piece 21a can be fitted into the stop hole 23d formed on the side surface 23c of the top cover piece 23a. Thereby, one top cover piece 23a can be attached to one bottom rail piece 21a, and the bottom rail 21 and the top cover 23 are assembled. Since the top cover piece 23a is made of synthetic resin, the stop hole 23d can be fitted into the protrusion 21g by slightly widening the side wall.

When the top cover 23 is assembled to the bottom rail 21, rail grooves 26 a and 26 b (FIG. 9) are formed in the bottom rail 21. Therefore, a long plate-like rack is formed between the pair of rail grooves 26 a and 26 b. The member 24 can be inserted.
In the coupled assembly type mechanism unit 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 in which 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 from the through hole 35, and the pinion gears 33 are respectively meshed with a plurality of opposing rack gears 25 (state of FIG. 6).
Specifically, by inserting the pinion member 31 from the through hole 35, the pin cylinder 34 of the pinion member 31 is supported by the through hole 35, and the shaft portion 31a on the other end side of the pinion member 31 is the support hole of the bottom rail piece 21a. It is supported by 21f.
At this time, all the rotation pins 36 of the pinion member 31 are oriented in the same state. The connecting and assembling mechanism portion 8 is fitted into the vertical frame 1, and the upper and lower ends 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 the opposite directions in the vertical direction, and the moving end is restricted by the stop material.

As described above, when attaching the top cover piece 23a, the bottom rail piece 21a, the pinion member 31, and the rack member piece 24a, and attaching the top cover 23, the bottom rail 21, and the rack member 24, a fixing tool such as an adhesive is used. Therefore, the removal of these members can be disassembled into individual parts in the reverse procedure described above. When disassembling, each member is made of synthetic resin and has elasticity, so that the members can be easily separated by expanding or bending the members.
After a plurality of assemblies 13 are connected, the procedure is the same as the first assembly procedure described above, and thus the assembly procedure of the rotation support portion 6 and the like described above is omitted.

Next, replacement of the movable louver 4 of the completed movable louver fitting 11 will be described with reference to FIG. FIG. 13A shows the situation on the side of the rotation support part, and FIG. 13B shows the situation on the side of the coupled assembly type mechanism part.
As shown in FIG. 13A, the support on the other end side of the movable louver 4 is released by cutting the resin-made pin 19 that supports the other end side of the movable louver 4 to be replaced. The movable louver 4 is removed from the frame 3 by moving the other end of the movable louver 4 to the outside of the frame 3 and removing one end of the movable louver 4. At this time, as shown in FIG. 13B, the rotation 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 movable louver 4 is inserted between the pivot pin 36 of the pinion member 31 and the pin 19, and the support hole 32 (see FIG. 9). The rotary pin 36 is fitted and the pin 19 is fitted into the pin hole 20 (see FIG. 8).

  As described above, the movable louver 4 can be easily replaced in a short time. In other words, for example, in a movable louver fitting in which all movable louvers are provided with one interlocking operation arm or the like, when replacing one movable louver, it is exchanged with an operation arm related to all movable louvers. Therefore, it was necessary to separate and install it from a movable louver, which required a large amount of work, requiring a lot of labor. On the other hand, in the louver joinery 11 of the present invention, since the coupled assembly type mechanism portion 8 is not directly related between the movable louvers 4, one movable louver 4 can be easily replaced in a short time. .

The open / closed state of the movable louver 4 in the louver fitting 11 will be described with reference to FIGS.
The state shown in FIG. 2A is a state in which the movable louver 4 is closed. As shown in FIG. 11A, one (left side in the figure) of the rack member 24 is positioned at the uppermost stage 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. 2B is a state in which the upper part of the movable louver 4 is tilted inward, and the movable louver 4 can be operated by pulling the upper part of any movable louver 4 or pushing the lower part. The upper part of the head is tilted inward so that the rotational position is maintained. That is, as shown in FIG. 11B, by tilting one of the movable louvers 4, one rack member 24 (left side in the figure) moves from the uppermost stage to the lower side via the pinion gear 33 and at the same time the other ( The right side rack member 24 moves upward from the lowermost stage, all the pinion gears 33 rotate counterclockwise, and all the movable louvers 4 rotate at the same angle to maintain the rotational position. The

  When the movable louver 4 is tilted in the horizontal direction, the movable louver 4 is tilted in the horizontal direction by holding the upper part of one of the movable louvers 4 or pushing the lower part, and the horizontal state is maintained. It will be in the state. That is, as shown in FIG. 11C, by tilting one of the movable 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 movable louvers 4 are rotated at the same angle, and the horizontal position is maintained.

The state shown in FIG. 2 (c) is a state in which the upper part of the movable louver 4 is tilted downward, and the upper part of the movable louver 4 is lowered by pulling the upper part of one of the movable louvers 4 downward. It will be in the state by which it was tilted and the rotation position was maintained. That is, as shown in FIG. 11D, by tilting one of the movable 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 in the counterclockwise direction, and all the movable louvers 4 are rotated at the same angle to hold the rotation position.
In the louver fitting 11 described above, the pinion gear 33 is rotated by rotating any of the movable louvers 4, the rack member 24 is moved in the axial direction via the rack gear 25, and the pinion gear 33 is moved via the other rack gear 25. By rotating, the plurality of movable louvers 4 are simultaneously rotated synchronously.

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

Next, the damage preventing action of the movable louver joinery when moving the moveable louver joinery in the lateral direction will be described.
The mounting frame 100 shown in FIG. 1A is in the closed position by the louver fitting 11 in the state of FIG. 1A, and the louver fitting 11 itself is also in the closed position with the movable louver 4 facing in the vertical direction. . When the movable louver 4 is closed, the louver joiner 11 can slide any louver joiner 11 in the lateral direction as a sliding door. FIG. 1B shows a state in which the mounting frame 100 is opened by sliding the front louver fitting 11a outward.
In the present embodiment, the louver joiner 11 can be slid only when the movable louver 4 of the louver joinery 11 is closed, and the louver joinery 11 cannot be slid when the movable louver 4 is inclined to some extent or horizontally. It has become.

Specifically, as shown in FIG. 14A, when the movable louver 4 is in the closed position, the rack member 24 to which the stopper pin 72 is attached is in the initial position, and each of the front louver joiner 11a and the rear louver joiner 11b. The stopper pin 72 is positioned at the lowered position, and the stopper pin 72 is not engaged with the stopper hole 73. Therefore, the mounting frame 100 can be opened by sliding the louver fitting 11 in the lateral direction. In FIG. 14, the cross section of the front louver joinery 11 a is shifted from the cross section of the rear louver joinery 11 b on the left and right of the chain line.
Specifically, as shown in FIG. 14A, with the attachment frame 100 in the closed position, the movable louver 4 is inclined or leveled to open the louver fitting 11. Then, as shown in FIG. 14B, one rack gear 25 of the pair of rack gears 25 is raised and the other rack gear 25 is lowered. Among these, since the stopper pin 72 is attached to the upper end portion of the rack gear 25 on the raised side, even if the stopper pin 72 is inserted into the upper stopper hole 73 and the louver fitting 11 is slid, the stopper pin 72 However, the movement of the louver joinery 11 is prevented. Therefore, when the movable louver 4 is in the open position, the louver joinery 11 cannot be moved, so that the movable louver 4 does not hit the adjacent louver joinery 11, and damage to the movable louver 4 or the louver joinery 11 can be prevented.

Therefore, when the louver joinery 11 is slid, the louver joinery 11 is returned from the open position of the movable louver 4 shown in FIG. 14B to the closed position as shown in FIG. 14A. You can move the slide.
FIG. 14C shows a state where the louver fitting 11 has moved to a place other than the closed position, and the stopper pin 72 is positioned at a place where the stopper hole 73 is not formed in the upper frame 100a of the mounting frame 100. . In this place, even if the movable louver 4 is opened, the stopper pin 72 hits the bottom surface of the upper frame 100a and the rack gear 25 cannot be moved upward. This prevents the movable louver 4 from opening. Alternatively, by shortening the length of the stopper pin 72, the rotation (inclination) of only a fixed rotation angle that does not allow the movable louver 4 to come into contact with others may be allowed. Therefore, since the movable louver 4 cannot be opened, the movable louver 4 does not hit the adjacent louver joinery 11, and the damage of the movable louver 4 or the louver joinery 11 can be prevented.
As described above, even when the louver fitting 11 is applied to the sliding door, the movable louver 4 does not interfere with the counterpart frame 3 during the sliding operation, and the operation function is not impaired.
On the other hand, when the rotation adjustment mechanism 90 of the movable louver 4 shown in FIGS. 15 and 16 is rotated in the direction in which the adjustment bolt 96 is tightened when the louver fitting 11 is in the closed position, the sleeve 98 presses the clamping plate 92a. The gap 95 is narrowed and the shaft hole 94d strongly clamps the extension 31b of the adjustment bolt 93, so that the pinion gear 33 can be prevented from rotating and the movable louver 4 can be prevented from rotating. Further, by adjusting the rotation of the adjusting bolt 96, there is an advantage that the turning resistance when the movable louver 4 is opened and closed can be adjusted.
In the case where the louver fitting 11 is arranged on the window of a windy day, even if the blown wind hits the movable louver, the rotation angle of the movable louver changes, or the movement of the movable louver due to mischief by children, etc. It is possible to prevent the moving angle from being changed.
It should be noted that the damage prevention mechanism for the movable louver joinery and the rotation adjustment mechanism 90 are arbitrarily provided in the louver joinery 11, and in the present embodiment, both are provided in one louver joinery 11 for convenience of explanation. It is described in the form.

Next, a second embodiment of the present invention will be described.
FIG. 18 shows a horizontal frame 40 on the upper side and a movable louver 41 disposed in the lower part of the horizontal frame 40. In this embodiment, the shapes of the upper and lower rails and the movable louver 41 are different from those of the above embodiment. About another structure, it is the same as the said embodiment. For convenience of explanation, the left side of the movable louver fitting in FIG. 18A will be described as the front surface (outside) of the movable louver fitting, and the opposite side will be described as the rear surface (indoor side).
The substantially flat horizontal frame 40 forms a cut 42 along the lower end portion of the horizontal frame 40 and from one end to the other end in the horizontal direction. The notch 42 is formed such that a notch having a substantially concave cross section is cut out only from the lower corner of the front side toward the rear side, and a lower end flange 43 protruding to the front side is formed at the lower end of the notch 42. The horizontal frame 40 is formed over the entire horizontal direction. Therefore, the thin portion 44 is located above the portion where the lower end flange portion 43 is formed. And the thin part 44 is formed in the perpendicular direction, the lower end collar part 43 protrudes to the horizontal direction front side, and the cross-sectional shape which combined the thin part 44 and the lower end collar part 43 is formed in L shape. The tip of the lower end flange 43 has a semicircular cross section.

A plurality of movable louvers 41 arranged below the horizontal frame 40 form an upper notch 47 along the upper end of the movable louver 41 and from one end to the other end in the longitudinal direction. . The upper notch 47 is formed such that a notch having a substantially concave cross section is formed in the lower corner of the rear surface side so as to cut from the rear surface toward the front surface side, and an upper flange portion 48 protruding to the front surface side is formed at the upper end portion of the upper notch 47. The movable louver 41 is formed over the entire lateral direction. Therefore, the thin part 49 is located below the part where the upper collar part 48 is formed. When the movable louver 41 is in the closed position, the thin portion 49 is formed in the vertical direction, the upper flange portion 48 protrudes rearward in the horizontal direction, and the cross-sectional shape of the thin wall portion 49 and the upper flange portion 48 is L. It is formed in a letter shape. The tip of the lower end flange 43 is formed in a semicircular shape.
The lower end side of the movable louver 41 forms a lower notch 51 along the lower end portion of the movable louver 41 and from one end to the other end in the lateral direction. The lower notch 51 is formed such that a notch having a substantially concave cross section is formed at the lower corner of the front side so as to be cut from the front side toward the rear side, and a lower flange 52 projecting to the front side is formed at the lower end of the lower notch 51. It is formed over the entire longitudinal direction of the horizontal frame 40. Therefore, the thin part 53 is located above the part where the lower collar part 52 is formed. And the thin part 53 is formed in the perpendicular direction, the lower collar part 52 protrudes to the horizontal direction front side, and the cross-sectional shape which combined the thin part 53 and the lower collar part 52 is formed in L shape. The tip end portion of the lower collar portion 43 is formed in a semicircular shape.

The position where the notch 42 of the horizontal frame 40 and the upper flange 48 of the movable louver 41 are formed is such that when the movable louver 41 is in the closed position, the tip of the upper collar 48 is in the notch 42 and the thin portion 44 of the notch 42 is. The position where the lower end flange 43 of the horizontal frame 40 and the upper notch 47 of the movable louver 41 are formed is in contact with the vertical wall surface. Make contact with a vertical wall.
Similarly, at the lower end and the upper end of each movable louver 41, the tip of the upper flange portion 48 of the movable louver 41 disposed below enters the lower notch 51 of the movable louver 41 disposed above, and is thin-walled. The tip of the lower flange 52 of the movable louver 41 arranged above enters the upper notch 47 of the movable louver 41 arranged below and contacts the wall surface of the thin portion 49. Like that. The protruding lengths of the lower end flange 43, the upper flange 48, and the lower flange 52 are made to coincide.
The explanation is omitted. As with the upper rail and the uppermost movable louver, the lower rail and the lowermost movable louver are each formed with a flange and a cut.

With such a configuration, when the movable louver 41 is in the closed position, the collar portions 43, 48, 52 corresponding to the notches 42, 47, 51 respectively enter. On the other hand, the thin portions 44, 49, 53 all extend in the vertical direction, and the flange portions 43, 48, 52 extend in the horizontal direction. Therefore, when the movable louver 41 is in the closed position, when light enters from the outside of the movable louver fitting, the joint between the horizontal frame 40 and the movable louver 41 and the movable louvers 41 at the upper and lower ends of the movable louver 41 When light hits the joint, the joint blocks light.
For example, when the light hitting the horizontal frame 40 and the uppermost movable louver 41 travels indoors, the reflected light passes downward between the upper flange portion 48 and the thin portion 44, and then the flange portion 43. The light reflected between 48 and 48 is directed in a direction opposite to the direction in which the light has entered. Therefore, although the reflected light is almost lost at this stage, it must pass between the flange 43 and the thin portion 49 after that. In this way, the reflected light must travel in a crank shape and effectively prevent light leakage by disappearing in the middle.
In this way, light leakage and direct sunlight can be reliably prevented, and the influence of the inside and outside air environment can be reliably cut off, contributing to energy saving effects by improving cooling and heating efficiency. become.

Next, a third embodiment of the present invention will be described.

Inside the vertical frame 82, a bottom rail 21, a top cover 23, a rack member 24, and a pinion member 31 formed by connecting the assembly 13 described in the first embodiment are disposed. Since these members are the same as those in the first embodiment, detailed description thereof is omitted.
The both ends of the U-shaped vertical frame 82 are formed with shielding portions 86 that protrude inward in the left and right (lateral) direction of the louver fitting 81 from the end surface of the bottom rail 21 on the movable louver 84 side. Further, the length L3 in the vertical direction when the movable louver 84 is in the closed position is formed to be smaller than the length L2 in the front-rear direction of the vertical frame 82. Therefore, as shown in FIG. 19, even when the movable louver 84 is oriented in the horizontal direction, the movable louver 84 does not interfere with the shielding portion 86.
In addition, although the case where the height L3 of the movable louver 84 is smaller than the longitudinal length L2 of the vertical frame 82 has been described, the height L3 of the movable louver 84 is desired to be larger than the length L2 of the vertical frame 82. As shown in FIG. 19C, both ends of the vertical frame 82 may be formed in a crank shape. That is, the vertical frame 82 is bent at a right angle at a portion where the vertical frame 82 is located on the side end surface of the movable louver 84, and is further bent in the longitudinal direction of the movable louver 84 at a position corresponding to the length of the movable louver 84. 86 may be formed.

Next, the operation of this embodiment will be described.
In the present embodiment, since the shielding portion 86 protruding toward the movable louver 84 is formed on the vertical frame 82, the clearance between the vertical frame 82 or the top cover 23 and the end surface of the movable louver 84 is covered with the shielding portion 86. Can do. Therefore, light leakage from between them can be prevented.
In this way, it is possible to reliably prevent light leakage and direct sunlight from entering 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.
