Description

TECHNICAL FIELD The present invention relates to a vertical louver type exterior wall technology, and more particularly, to an exterior wall technology that makes it possible to change the angle of a plurality of vertically arranged louvers for each predetermined divided range.

Whether vertical or horizontal, there are many fences made of wood, metal, or resin that are fixed to a grid-like frame. Meanwhile, there are some shutters and fences with louver structures. However, whatever type of existing wall has the function of blocking the line of sight, it is inconvenient because the room becomes dark and the ventilation is poor.

There are fences that keep the room bright while blocking the line of sight, and fences that only let in light, such as translucent acrylic plates. In addition, there are louvers that can block the line of sight and that have a variable function such as opening the louvers to adjust when it is desired to let the wind through. However, when they block the line of sight, all the louvers are closed, so the ventilation becomes poor, and the line of sight cannot be blocked even if only a part of the louver is allowed to pass through. It can be said that there is a demand for walls and fences that block the line of sight and at the same time improve ventilation.

Moreover, it is not only the line of sight from the outside that is of concern, but also noise should be avoided. However, if the louvers of existing walls and fences are closed to reduce noise from the outside, ventilation and indoor light will also be blocked. There are no walls or fences that can

A louver can be mentioned as a wall or similar to a fence that can take in wind and light, but there are various types of louvers. There are also type louvers. One of the features of vertical louvers is that they are easy to clean because dust does not accumulate easily. Another feature of vertical louvers is the directionality of the line of sight. For example, you can't see it from the outside, but you can see the outside well from one direction inside. As a result, it is possible to observe the situation outside only from the inside without being noticed from the outside. However, there is a need for a vertical variable louver that allows different ranges to be varied independently.

In order to solve the above problems, we would like to pay attention to the changeable blades as a louver that can be used for multiple functions at the same time. Conventionally, there are louvers that change the angle of the blades.

Therefore, various technical proposals have been made in the past. For example, a technique entitled "Balcony" is disclosed (see Patent Document 1). Specifically, "to provide a balcony capable of efficiently letting the wind into the inside of a living room behind an opening, preventing the inside of the living room from being seen even from the front, and controlling the wind." As a solution, the balcony handrail consists of an opaque wall provided in front of the opening and a window provided on the left or right side of this wall, and a louver lattice is attached to this window.This louver For the lattice, a plurality of louver pieces were attached substantially parallel with gaps between them." The invention described in Patent Document 1 has a point in common with the present invention.

Also, a technique entitled "louver type floor" is disclosed (see Patent Document 2). Specifically, the challenge is to "provide a louver-type floor that can take in sunlight and wind when necessary through the floor of a balcony or veranda." A plurality of movable louver floor members arranged side by side and a rotating means for vertically rotating the plurality of louver floor members are provided. The rotating means rotates the plurality of louver floor members. By rotating the louver floor members upward, a gap is formed between the adjacent louver floor members, so that sunlight and wind can be taken in through the gap when necessary, and the louver floor member can be lifted from the upright state by the rotating means. By pivoting downward, these louver floor members can be leveled to prevent sunlight, wind, and rain from penetrating through the floor of the verandah."

Also, a technique entitled "exterior louver device" is disclosed (see Patent Document 3). Specifically, the object is to "provide an exterior louver device that enables smooth fixing and opening of the louver without impairing the appearance, and in which an entrance is formed." an upper horizontal frame having a rail provided with the horizontal direction as a longitudinal direction, a lower horizontal frame having a rail provided parallel to the upper horizontal frame at a predetermined interval below the upper horizontal frame, and an upper A plurality of louvers arranged vertically so as to span the horizontal frame and the lower horizontal frame and arranged in parallel in the longitudinal direction of the upper horizontal frame and the lower horizontal frame at a predetermined interval; At least a pair of moving means having moving wheels, one end of which is provided with the wheels being movable along the rail, and the other end being attached to one of a plurality of louvers and provide.”

Also, a technique entitled "Structure for Creating an Intermediate Area Inside and Outside a House" has been disclosed (see Patent Document 4). Specifically, it is possible to adjust the intake of sunlight and ventilation according to the season and usage conditions, the shielding from other people's eyes, etc., and at the same time, it is possible to assist the temperature control inside the house. The challenge is to provide a structure that creates a space called the intermediate area between.” As a solution, we have established “left and right vertical frames on the outside of the outer wall of the house, and upper walls provided at the top of these vertical frames. A large number of louvers are slidable along the upper frame inside the frame, which is composed of left and right vertical frames and upper and lower horizontal frames. In addition to providing a sliding panel with a hanging louver, a roof was provided between the upper frame and the outer wall, and an intermediate area was provided between the sliding panel and the house."

Further, a technique titled "installation structure of vertical louver" is disclosed (see Patent Document 5). Specifically, for a beam-shaped structure such as a wall surrounding a loggia, where exterior wall panels are stretched on both the indoor and outdoor sides of the beam material made of H-shaped steel in advance, a large vertical To provide a vertical louver installation structure that enables easy post-installation of louvers with a rational fit. A plurality of vertically long slats are arranged in parallel at regular intervals inside the frame, and the upper ends of the slats are suspended from support rails forming the upper side of the frame to rotate about a vertical axis. When installing the vertical louver configured to obtain the vertical louver directly under the beam-shaped structure in which the exterior wall panels are stretched on both indoor and outdoor sides of the beam material made of H-shaped steel, the cross section perpendicular to the length direction is horizontally long The support rails, which are formed to form a rectangle of It is premised."

As described above, the present invention has common problems with the inventions disclosed in Patent Documents 1 to 5, which are publicly known technologies. However, none of Patent Documents 1 to 5 describes or suggests an exterior wall technology that enables changing the angle of a plurality of vertically arranged louvers for each predetermined divided range.

The present invention provides a vertical louver type outer wall comprising a plurality of vertically arranged louvers, a base provided with the louvers, and an opening/closing angle adjusting mechanism for adjusting an opening/closing angle of the louvers. The greatest feature of the louver is that it consists of divided regions connected by connecting members that share the same opening and closing angle, and that the opening and closing angle of the louver can be varied differently for each of the divided regions. be. Description will be made below with reference to the drawings. However, the shape and configuration are not limited to those described in the drawings, and can be changed within the range where the effect exhibited as the creation of the technical idea of the present invention can be obtained.

FIG. 1 is an explanatory diagram of the basic configuration for explaining the basic configuration of the vertical louver type outer wall according to the present invention. Each configuration will be described in detail below.

The vertical louvered outer wall 1 is composed of a plurality of vertically arranged louvers, a base having the louvers, and an opening/closing angle adjusting mechanism for adjusting the opening/closing angle of the louvers. The basic configuration is that the plurality of louvers are formed by dividing regions connected by connecting members that share the opening and closing angles of the louvers, and that the opening and closing angles of the louvers are changed differently for each of the divided regions. do.

The louver 10 is a general term for a plurality of elongated plates, also called louvers, or louver-shaped members arranged in parallel. Depending on the angle of the louver 10, it is possible to block sight lines, sunlight, wind and rain, noise, etc. from the outside. It is used in various places, including buildings, such as for hiding lighting fixtures and air conditioners. It is also used to design roof facilities and outdoor stairs integrated with the building for landscape protection. Also, the longitudinal direction of the louvers 10 may be arranged vertically or horizontally depending on the place of use. Looking at the cross section of the louver 10, as shown in FIG. 2, it is shaped like a Japanese katakana letter M, and the other side cannot be seen from the front, but can be seen by shifting the viewpoint. In some cases, the angle of the slats can be adjusted in order to change the amount of wind passing through. The opening and closing angle can be varied for each.

The material of the louver 10 is not particularly limited, and various materials such as wood, metal such as aluminum, and resin can be used as long as the material has a high specific strength that can withstand external forces such as strong winds. . However, in the vertical louver type outer wall 1 according to the present invention, since the louvers 10 are arranged vertically, strength against buckling is required. For example, it is more preferable to use a hollow double structure made of aluminum. Also, as for the shape, it is desirable that the louver 10 is not simply a plate-like wing plate, but has a wing shape, as shown in cross section in FIG. . This is because such a shape can prevent the occurrence of swirl (turbulent flow) when the air flows, thereby suppressing wind noise.

The base 20 is a pedestal for providing a plurality of louvers and the opening/closing angle adjustment mechanism 30, and is configured by a strong housing. It is desirable that the louver 10 has a certain weight so that it can be firmly fixed even if it is affected by the wind, or that it is fixed with an anchor bolt or the like.

The opening/closing angle adjusting mechanism 30 is a mechanism for adjusting the opening/closing angles of the plurality of louvers 10. The plurality of louvers 10 within a predetermined area are manually adjusted for each area R where the opening/closing angles are shared by connecting members. Alternatively, it is provided to be electrically driven. As for the driving method, it is conceivable to use a means using a link mechanism, a combination of a cam and a pushrod, a rack and pinion system, or a control means using a motor that provides positioning and holding force for positioning by a servo motor or stepping motor. . However, for example, it is also possible to replace the cam and push rod with an eccentric sprocket and a chain drive, etc., and unless otherwise specified, it is not limited to these means, and as a creation of the technical idea of the present invention It can be changed as long as the same effect can be obtained.

The connecting member 40 is a member that connects the plurality of louvers 10 in order to unify the opening and closing angles. The drawing shows a state in which three louvers 10 are connected as one region, but the number and attachment positions are not limited. It should be noted that the use of bearings such as pillow balls and bearings is preferable from the point of view of smooth operation.

The link mechanism 31 is a mechanical element that operates the series of louvers 10 connected by the connecting member 40 so as to form a predetermined opening/closing angle. In the embodiment shown in FIG. 3(a), when the arm is rotated, the position of the distal end changes depending on the position, and the opening/closing angle of the louver 10 is determined according to such change. Note that the link mechanism may be combined with mechanical elements such as the cam 32 and the rack gear 34 .

Cam 32 is a mechanical element that changes the direction of motion. In a mechanical device, the side that transmits the motion is called the primary joint, and the side that receives the motion and performs work is called the follower, and the cam 32 corresponds to the primary joint. For both cams, which have linear reciprocating motion and rotary motion, the time and distance that the follower end moves is determined by the shape and speed of the prong. As in the embodiment shown in FIG. 3(b), the rotating cam 32 is attached to the shaft and has a curved surface corresponding to the rotation angle of the shaft. In general, a plate with an irregular distance from the center to the circumference, called a disk cam typified by an oval shape, is attached to the rotating shaft, and the rod in contact with this plate is pushed and pulled linearly. It is. In the vertical louver type outer wall 1 according to the present invention, the shape of the cam 32 is such that the cam 32 protrudes from the center to push out the rod that contacts the cam 32, and the trough is formed to pull the rod. A follower such as a roller is pressed by the connecting member 40 to push and pull the connecting member 40 so that the series of louvers 10 connected by the connecting member 40 are operated to have a predetermined opening/closing angle. Compared to other mechanical elements, failures are less frequent, extremely stable operation is possible, and a structure that does not apply unnecessary force to the machine can be constructed, so that the vertical louver type outer wall 1 according to the present invention can be made to have a longer life. be able to.

The push rod 33 performs linear motion between a follower such as a roller in contact with the cam body and an operating end. 50 or the like is operated to convert a rotational motion within a certain rotation angle range into a linear motion.

The rack gear 34 is a type of gear used in a rack and pinion system, and converts rotational force into linear motion. As shown in FIG. 3(c), a small-diameter circular gear called a pinion gear 35 is combined with a rack gear 34, which is a flat plate-shaped rod with a tooth cut. is linearly driven in the horizontal direction to the end where the tooth trace is set.

Pinion gear 35, a small gear, or the smaller gear of a pair of meshing gears, as shown in FIG. In other words, it is a mechanical element that converts rotary motion into linear motion.

The servomotor 36 is an electric motor used for controlling the position, speed, etc. of the output shaft of the motor. As the type of motor used in the vertical louver type outer wall 1 according to the present invention, it is preferable to use an electric motor with a rotational position detector such as a rotary encoder, which is feedback-controlled. As a feature of the servomotor 36, it is preferable to use one with a speed reducer using gears in order to generate torque in the medium to high speed range. Note that FIG. 4 assumes a geared head with a speed reducer.

The stepping motor 37 is a motor that is driven by applying a DC pulse voltage via a driver, and is also called a pulse motor. Since accurate positioning control can be realized with a simple circuit configuration, it can be said to be suitable for positioning the opening/closing angle of the louver 10 . Features include momentum proportional to the number of drive pulses, good compatibility with digital control circuits, and no need for a feedback circuit, generating large torque in the low rotation range, and stopping It can be said that the motor is most suitable as an electric drive for the opening/closing angle adjusting mechanism 30 because the holding force for holding the position is large. If the load is too large or the pulse frequency is too high, synchronization may be lost and control may be disturbed (step out). In addition to the configuration in which the stepping motor 37 is arranged for each predetermined area, a configuration in which the stepping motor 37 is arranged for each of the plurality of louvers 10 as shown in FIG. A single stepper motor 37) is also conceivable.

The lever 50 is a member that operates the series of louvers 10 connected by the connecting member 40 so as to form a predetermined opening/closing angle. Note that the lever 50 may be a crank depending on the relationship between the operating range and the movable range.

A region R means a region in which a predetermined number of louvers 10 are arranged, and FIG. 2 shows one region R divided into three louvers. Although the number of louvers 10 is not limited, it is desirable to set the number to a suitable number because the greater the number of louvers 10, the greater the burden on the operating levers 50, the motors, and the like.

FIG. 2 is an operating state explanatory diagram showing an embodiment in which the opening and closing angles of the louvers for each predetermined region are adjusted in the vertical louver type outer wall according to the present invention, and illustrates a state in which the entire louver 10 is divided into three. . 2(a) shows a state in which all of the louvers 10 are inclined, FIG. 2(b) shows a state in which all of the louvers 10 are fully closed, and FIG. 3(d) shows a state in which the louvers 10 in the central region are fully opened and the left and right regions are inclined in different directions, and FIG. 2(e) shows a state in which the central region is fully opened. The left and right regions of the closed state show the fully open state. It should be noted that this configuration is merely an example, and although not shown in the drawings, it is possible to assume that similar effects can be exhibited in other configuration examples in which the opening and closing angle of the louver 10 is adjusted for each region R. included in the range.

3A and 3B are diagrams for explaining the operating principle of the opening/closing angle adjusting mechanism according to the present invention, and FIG. 3(b) shows the operation principle of the opening/closing angle adjustment mechanism 30 when the operation principle is the cam 32 and the push rod 33, and FIG. 3(c) shows the operation principle of the opening/closing angle adjustment mechanism 30. 3(d) shows the operating principle of the opening/closing angle adjusting mechanism 30 using the servomotor 36, and FIG. The operation principle of the angle adjusting mechanism 30 is shown when the stepping motor 37 is used.

As shown in FIG. 3A, when the operating principle of the opening/closing angle adjusting mechanism 30 is the link mechanism 31, it can be constructed with simple mechanical element members, so that it can be manufactured at low cost, and bearing members such as pillow balls and bearings can be manufactured. By using , it is possible to obtain smooth operation.

Further, as shown in FIG. 3B, when the operation principle of the opening/closing angle adjusting mechanism 30 is the cam and the push rod 33, it can be constructed with simple mechanical elements and is excellent in durability. Although FIG. 3B shows a configuration in which one cam 32 is used for one region R, a plurality of regions R may be driven by one cam 32 . In such a configuration, the cam 32 has a complicated shape and becomes large, but it is possible to reduce the number of parts and work steps.

Further, as shown in FIG. 3(c), when the operation principle of the opening/closing angle adjusting mechanism 30 is the rack gear 34 and the pinion gear 35, the rotary motion can be changed into the linear motion by a simple mechanical element member. It can be said that this mechanical element is suitable for the opening/closing angle adjustment mechanism 30 for the vertical louver type outer wall according to the invention. Although not shown in the drawings, it is also preferable to replace the pinion gear 35 with a worm gear and the lever 50 with a crank to reduce the operating force.

Further, as shown in FIG. 3D, when the servomotor 36 is used for the operating principle of the opening/closing angle adjustment mechanism 30, first, as a feature of the servomotor 36, since torque is generated in the middle and high rotation range, the angle is adjusted at low speed. In the present invention, in which only changes are made, it is preferable to use a device with a speed reducer using gears. Note that FIG. 4 assumes a geared head with a speed reducer.

Also, as shown in FIG. 3(e), when a stepping motor 37 is used for the operating principle of the opening/closing angle adjusting mechanism 30, it is preferable to use a gear-reduced gear-equipped motor similar to the servomotor 36. . In addition, FIG. 4 assumes a geared head with a speed reducer, and shows a case where one stepping motor is arranged in one louver 10, and the opening/closing angle of each louver 10 varies depending on the number of pulses. In response, the angular position is rotated to a predetermined angle and the position is held by pulse control, which can also be achieved by simple sequence control.

FIG. 4 is an explanatory diagram of the usage state according to the present invention. In the embodiment shown in FIG. 4, the five louvers 10 arranged in the left area R1 are inclined toward the user H side, and the five louvers 10 arranged in the central area R2 are open to the user H side. The five louvers 10 arranged in the region R3 on the right side are arranged so as to be closed to the user H side, but the blindability and ventilation differ depending on the position of the user H. . At position A, ventilation is ensured in the left region R1 and the central region R2 while blinding through the left region R1, the central region R2 and the right region R3. In addition, in the position B, the visibility of the left region R1 and the central region R2 is improved, while the right region R3 is a use example in which blinding and sound insulation are enhanced. Moreover, it can be said that position C is the position where the most effective blinding and sound insulation effects can be obtained. However, this is only an example, and there are various cases where the purpose of partial opening and closing is different, such as a part where you want to enjoy the scenery, a part where you want to shield from noise and exhaust gas, or a part where you want to be blinded from the outside but also want to ventilate. FIG. 4 shows an example of what can be done to deal with these problems.

According to the vertical louver type outer wall 1 according to the present invention, it is possible to ensure breathability, sound insulation, and heat retention while blocking the line of sight from the outside, which everyone wants in daily life. Since it is a technology that can provide a space that emphasizes comfort, it is considered to have high industrial applicability.
