Japanese Patent Laid-Open No. 2002-47868

  When a movable louver is applied to a wooden joinery, it is necessary to provide a storage space in the vertical gutter for the convenience of storing the functional part that performs synchronous adjustment of the inclination angle of the movable wing in the vertical gutter. In order to secure the strength of the joinery after providing a space, it was necessary to widen the vertical fence. On the other hand, in aluminum fittings that use movable louvers, since robust aluminum molds are used as frames, for example, movable wings can be applied to fittings with relatively narrow walls such as indoor three-story sliding doors. Sufficient strength can be secured at the time of forming the joinery, but in the case of wooden joinery, if the space for storing the above-mentioned functional part is provided in a narrow vertical fence, the strength cannot be maintained and the application of the movable louver must be narrowed. There was no current situation.

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide a wooden movable louver that can be attached to an opening under various conditions indoors and outdoors while maintaining sufficient strength.

The wooden movable louver of the present invention includes a wooden frame that forms a frame along the indoor and outdoor openings of the building, and a large number of movable wings that are rotatably supported between the vertical shafts of the wooden frame. The vertical shaft is formed in a substantially U-shape with the inner peripheral side surfaces thereof open and recessed grooves inside, and each movable wing has a gear on at least one shaft portion, The gear includes a rack that can mesh and move up and down, and the rack is attached to the inner peripheral side of a reinforcing member that is disposed so as to surround the front, rear, left, and right sides of each gear and is movable in the vertical direction. It is formed so that the inclination angle of each movable wing can be synchronously adjusted by moving up and down, and the reinforcing member is detachable by being fitted into a concave groove on the inner periphery side of the vertical shaft .

  Here, the front, rear, left, and right directions are based on a state in which the wooden movable louver is viewed from the front. In addition, since the application location of the wooden movable louver can be used regardless of the inside or outside of the building, such as a window or a partition door, the front, rear, left, and right directions described above can be used indoors, outdoors, and adjacent rooms depending on how the wooden movable louver is used. Etc. In addition, the reinforcing member disposed so as to surround the gears needs to be in a form that does not prevent vertical movement of the rack and rotation of each gear, as well as ensuring the strength of the vertical shaft. What is necessary is just to form in the cylinder shape, box shape, etc. which continue up and down along the longitudinal direction.

  When formed as described above, the rack that meshes with the gears of the shafts of the movable blades and applies a rotational force moves up and down in the reinforcing member interposed in the vertical shaft, so that the reinforcing member is Each gear and rack in meshed state can be accommodated inside while playing the role of core material in the vertical shaft.

The reinforcing member, since it is detachable fitted into the concave groove of the vertical frame inner periphery, functional portion (eg gears, racks, etc.) a reinforcing member for each vertical for adjusting synchronization of the inclination angle of the movable vanes It is possible to use it by removing it from the inside of the cage and attaching it to the vertical cage again after the inspection.

According to the present invention, even when the functional part for performing the synchronous adjustment of the inclination angle of the movable wing is accommodated in the vertical wall of the wooden joinery, it is accommodated via the reinforcing member, for example, indoors Even for wooden fittings that have to be thinned down, such as sliding doors, movable wings can be applied while ensuring sufficient strength, and therefore wooden that can be used for indoor and outdoor openings in various buildings. A movable louver can be provided. Also, the movable blade and the gear, by a reinforcement member such as with the rack can be detached from the groove in the stile, the maintenance function portion for performing a synchronization adjustment of the inclination angle of the movable blade can be easily.

Hereinafter, embodiments of the wooden movable louver according to the present invention will be described with reference to the drawings.
As shown in FIG. 1, the entire structure of the present wooden movable louver is composed of an upper beam 2 and a lower beam 3 that form a wooden frame to be installed in the indoor opening L of the building, and the vertical beams 1a and 1b arranged in parallel on the left and right In between, a plurality of wooden movable blades 4 are vertically supported at equal intervals in the vertical direction so as to be vertically rotatable via shaft portions 5, and gears 6 are respectively provided at the tips of the shaft portions 5. Yes. A vertical groove 1a on the right side of the front view is provided with a groove S extending along the longitudinal direction of the vertical wall 1a, and the rectangular tube-shaped core member that coincides with the groove S is provided in the groove S. 8 is detachably attached, and a rack 7 that moves up and down along the guide groove V is provided on the inner back side of the core member 8. The rack 7 is engaged with the gears 6. 7, the inclination angle of each movable wing 4 is adjusted synchronously.

Further, the vertical movement of the rack 7 in the core member 8 is performed in conjunction with the operation lever 9 provided on the upper part of the lower rail 3. Specifically, as shown in FIGS. 2A and 2B, a transmission unit 10 is interposed for converting the movement of the operation lever 9 sliding left and right into the vertical movement of the rack 7. For example, as shown in FIG. 2A, the transmission unit 10 has a specific configuration in which a spur gear 13a meshes with a transmission rack 12 on the back side of the operation lever 9 when the operation lever 9 is slid to the right. Is rotated clockwise, and the driving bevel gear 11a provided integrally with the spur gear 13a is also rotated at the same time. The drive bevel gear 11a meshes with a driven bevel gear 11b pivotally supported on the right part of the transmission unit 10, and the driven bevel gear 11b rotates counterclockwise as the drive bevel gear 11a rotates. Then, the driven bevel gear 11b and the spur gear 13b attached via the shaft simultaneously rotate counterclockwise, and the spur gear 13b and the rack 7 mesh with each other, so that the rack 7 moves downward. Accordingly, the inclination angle of each movable wing 4 is adjusted synchronously so as to become horizontal from the standing state.
FIG. 2B shows the movement of the transmission unit 10 when the operation lever 9 is slid to the left. In this case, the rack 7 is moved upward as opposed to the above-described sliding to the right. The movable blades 4 are moved and adjusted in synchronism so as to change from the horizontal state to the upright state.

Next, each structure of the attachment part with the core material 8 used as the principal part of this wooden movable louver and the vertical rod 1a of this core material 8 is demonstrated below.
As shown in FIG. 3, the core member 8 has a rectangular tube shape that matches the concave groove S of the vertical rod 1 a. A guide groove V is provided in the peripheral wall 14 on the back side of the peripheral walls forming the core member 8, and the rack 7 is provided in the guide groove V so as to be slidable in the vertical direction. Further, the peripheral wall 15 on the left side of the core member 8 when viewed from the front is provided with a number of bearing holes 17 for receiving the protrusions of the shaft portions 5 of the movable blades 4 at regular intervals. For attaching the core member 8 and the vertical rod 1a, the core member 8 is inserted from the front side of the concave groove S of the vertical rod 1a, and the shaft portion 5 protruding from the peripheral wall 16 on the right side of the core member 8 when viewed from the front. The core 8 is formed so as not to come out downward from the concave groove S of the vertical rod 1a by engaging the tip with the receiving hole 18 provided on the vertical rod 1a side (see FIG. 4).

  Further, the core material 8 can be attached to the vertical gutter 1a concave groove S as follows. In this attachment procedure, as shown in FIG. 5, the peripheral walls 14, 16, and 19 constituting the core material 8 are disposed in advance in three directions in the concave groove S, and further, a space is provided above and below the peripheral wall 16 on the left side when viewed from the front. Each shaft portion 5 through which the gear 6 is opened is protruded and the tip of each shaft portion 5 is engaged with each receiving hole 18 of the vertical rod 1a, while three sides are surrounded by each peripheral wall 14, 16, 19 In the gear running space R, the gears 6 and the rack 7 are engaged with each other. In addition, the remaining one peripheral wall 15 is attached to the open part on the left side of the core member 8 when viewed from the front. At this time, the other tip of each shaft portion 5 is provided with each bearing hole 17 provided above and below the peripheral wall 15. Further, the other tip of each shaft portion 5 protruding from each bearing hole 17 in the peripheral wall 15 can be inserted into the side surface of each corresponding movable blade 4 to pivotally support each movable blade 4.

  As shown in FIGS. 6 (a) and 6 (b), the core material 8 is accommodated in the concave groove S of the vertical rod 1a as described above. The gear 6 of the shaft portion 5 that has entered the bearing hole 17 is engaged with the rack 7, and the vertical movement of the rack 7 gives a rotational force to the gear 6. Alternatively, it is arranged to resist the external force applied from the side from the inside of the vertical gutter 1a, so that the strength of the vertical gutter 1a is maintained. The wooden movable louver can be applied in various modes independent of the thickness of the vertical gutter 1a.

FIG. 7 shows another embodiment of the present invention. This wooden movable louver incorporates a speed reduction unit 20 inside the louver body so that the knob 9 can be moved with a relatively light force when each movable wing 4 is opened and closed. Formed. As shown in FIGS. 8A and 8B, the specific structure of the speed reduction unit 20 is linked to the sliding of the knob 9 to the left and right, and each of the driving and driven caps engaged with each other at right angles. Between the gears 11a and 11b and the spur gear 13b that moves up and down the rack 7 that applies a rotational force to each movable blade 4, the large and small four reduction gears 21a, 21b, 21c, and 21d are respectively meshed. They are configured together. When the reduction gears 21a, 21b, 21c, and 21d are engaged with each other as described above, the sliding distance of the knob 9 is increased in order to rotate the movable blades 4 at an angle inclined downward from the horizontal position. However, the movement of the knob 9 when sliding is significantly lighter, and the feeling of use is dramatically improved as compared to the case where the sliding amount of the knob 9 and the distance that each movable wing 4 rotates is the same. It will be.
In the present embodiment, the gear ratio of each of the reduction gears 21a, 21b, 21c, and 21d of the reduction unit 20 is such that the rotation distance by which the movable blade 4 is variable from the horizontal position (open state) to the inclined position (closed state). If it is 1, the distance that the knob 9 slides is set to be 4. However, if the gear ratio is such that the load when the knob 9 is slid is clearly felt, the setting is particularly effective. It is not intended to be limited.

Further, as shown in FIG. 9, the knob 9 of the present embodiment has a structure that is hidden by a part of the louver body when viewed from the front. Specifically, the knob 9 is arranged on the upper side of the louver body where the movable blades 4 are arranged. A slit 23 for inserting a finger is provided between the portion and a lower portion in which a portion related to the rotation of each movable wing 4 is stored. On the upper side of the slit 23, a downward concave groove 24 is formed, and the slider 9 slides along the groove 24 so that the rack 23 passes through the reduction gears 21a, 21b, 21c, 21d of the reduction unit 20. 7 is moved up and down to transmit the rotational force to each movable blade 4. When the knob 9 is arranged as described above, the wooden movable louver looks like a design in which the movable wing 4 is fixed at a predetermined angle when viewed from the front. If 9 is slid left and right, each movable wing 4 can be opened and closed, so that it is possible to enjoy the unexpectedness of the design.
