Japanese Patent Laid-Open No. 10-148069

  Here, there is a fitting that blocks a line of sight from the outside by arranging a plurality of thin plate-like horizontal louvers in a vertical direction in a window portion of the building. When the thin plate-like horizontal louvers are inclined in the width direction, the ventilation function can be realized, but it is insufficient as a function of reducing visibility from the outside. Depending on the line of sight from people outside the building, the room could be seen, making it difficult to ensure privacy. Specifically, when viewed from the direction along the inclined surface of the horizontal louver, the horizontal louver is only arranged in a line, it cannot block the line of sight, and the inside of the building can be seen from the outside It was in a state that could be done.

  Then, it aims at providing the fitting structure which can ensure a ventilation function while ensuring a ventilation function, and the installation structure of a fitting.

The joinery of the present invention is a joinery that covers an opening of a window portion of a building and has a blindfold function that reduces visibility in the window portion and a ventilation function that secures an air flow, and includes a plurality of first portions on the upper side of the window portion. An upper shielding part in which one horizontal louver is arranged in the vertical direction, and a lower shielding part in which a plurality of second horizontal louvers are arranged in the vertical direction below the upper shielding part . One horizontal louver is inclined such that the indoor side is arranged above the outdoor side, and the plurality of second horizontal louvers have a central portion in the width direction in the cross section of the second horizontal louver as a vertex and cross from the vertex. Inclined downward to both sides of the surface in the width direction .

  In this fitting, the lower shielding part has lower visibility than the upper shielding part, and the upper shielding part has higher ventilation performance than the lower shielding part. When an outside person sees the window, the line of sight is obstructed by the lower shielding part, so that it becomes difficult to see the floor surface of the room and the lower side of the person's body in the room. As a result, the lower level of occlusion (difficulty of visibility), where privacy is more important, is increased, and the lower level, the lower level of occlusion is less important in the lower part, and ventilation performance is increased instead. As a result, it is possible to ensure both privacy and ventilation.

Here, the plurality of first horizontal louvers are inclined such that the indoor side is disposed above the outdoor side, and the plurality of second horizontal louvers have a central portion in the width direction in the cross section of the second horizontal louver. an apex, it is inclined downward to the both sides in the width direction of cross section from the apex. In this configuration, the first horizontal louver of the upper shielding unit is inclined such that the indoor side is disposed above the outdoor side, and therefore the upper surface of the first horizontal louver faces obliquely upward toward the outdoor side. It becomes. When an outside person looks at the window, the upper line of sight disturbs the downward line of sight, making it difficult to see the indoor floor and the lower side of the room. In addition, the second horizontal louver of the lower shielding portion is inclined downward to both ends in the width direction with the central portion in the width direction in the cross section as the apex, so that the cross section is a square shape (inverted V shape) The outer side portion of the second horizontal louver forms a surface that faces obliquely upward toward the outdoor side, and the indoor side portion of the second horizontal louver is obliquely upward toward the indoor side. A surface facing the surface is formed. Since the second horizontal louver is bent in the width direction in the cross section, for example, the line of sight that has passed through the gap in the outdoor portion is blocked by the indoor portion arranged to bend from the outdoor portion. . In the second horizontal louver, the angle of the line of sight that can be blocked differs between the outdoor portion and the indoor portion, so that the region that can block the line of sight can be widened. When the plate-like horizontal louver is tilted at a predetermined angle, it is difficult to block the line of sight parallel to the tilt angle, but the second horizontal louver can be bent and arranged in the width direction in the cross section. , The area that can block the line of sight can be widened. Therefore, it is possible to further increase the degree of shielding at the lower portion where privacy is more important.

  Further, in the second horizontal louver adjacent vertically, a virtual straight line connecting both ends in the width direction in the cross section of the second horizontal louver located above intersects the second horizontal louver located below or It is preferable that they are arranged so as to contact each other. In this configuration, it is difficult to visually recognize through the gap between the second horizontal louvers adjacent in the vertical direction, and it is possible to reliably block the line of sight in the lower blocking portion.

  The first and second horizontal louvers may be formed of a light-transmitting material that transmits light. Accordingly, the upper shielding part and the lower shielding part can be configured using a horizontal louver that transmits light, and light can be taken into the room while ensuring a blindfold function and a ventilation function. In the lower shielding part, the second horizontal louver is arranged so as to overlap in the width direction in the cross section, so that the state of the room can be clearly seen and the lower shielding part is lower than the upper shielding part. The visibility of can be reduced.

  In addition, the second horizontal louver is higher in rigidity than the first horizontal louver, and a connecting member for connecting the plurality of first horizontal louvers is attached to an intermediate portion in the longitudinal direction of the first horizontal louver. The structure extended to an up-down direction and the lower end of a connection material is supported by the 2nd horizontal louver is mentioned. According to this configuration, the first horizontal louver is supported from below by the connecting member, and the connecting member is supported by the second horizontal louver having higher rigidity than the first horizontal louver. The bending in the longitudinal direction can be suppressed.

  The connecting member is preferably formed with a notch that engages with the first horizontal louver. When a notch that engages with the first horizontal louver is formed in the connecting member, a plurality of first horizontal louvers arranged in the vertical direction can be obtained simply by inserting the connecting member into the first horizontal louver. Can be held together. Since the notch part is formed in the connection material, it can connect using a connection material, without processing the 1st horizontal louver. By suppressing the bending of the first horizontal louver and arranging it at a predetermined position, it is possible to achieve both the blinding function and the ventilation function in the upper shielding part.

It can correspond to the position of the human eye. For example, the line of sight from a person passing through a road facing the window on the first floor of the building can be blocked by the lower blocking unit.

  In addition, the installation structure of the joinery of the present invention is a joinery installation structure in which the joinery is installed with respect to the window portion, the window portion includes a plurality of shojis, and the joinery has the window portion opened. The first and second horizontal louvers have both ends supported by the frame, and the joinery is slidable along the width direction in the front view of the window. It is characterized by being.

  In the installation structure of this joinery, one joinery can be comprised as a structure provided with the frame body which supports the both ends of the 1st and 2nd horizontal louver. By setting it as the installation structure provided with only one piece of joinery, the thickness of the joinery can be suppressed.
