Description

  The present invention relates to a door having a ventilation function.

  Conventionally, a door having a lower heel part that is open and closed is known, but it must be bent when opening and closing, which is inconvenient. Moreover, since warm air rose, it was not possible to ventilate efficiently when the opening was only at the bottom. Therefore, by providing a vertical louver over the entire length of the door in the vertical direction, it can be easily opened and closed while standing and can be efficiently ventilated. However, since there is an opening at the height of the human eye, passing through the line of sight becomes a problem. Therefore, the door of patent document 1 is set as the structure by which a rotation cover member is always arrange | positioned in front of an opening part, and has interrupted the line of sight from the outside with a rotation cover member.

JP 2003-161082 A

  However, when the door of Patent Document 1 is viewed from the front in the open state, the line of sight is blocked by the rotating lid member, but the line of sight passes through the opening when approaching the door, so that the line of sight is sufficiently blocked. That's not true.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door that can block the line of sight from the outdoor side toward the center of the room even when there is an opening at the height of the line of sight.

  The invention of claim 1 of the present invention comprises a door, a vertically long opening provided in the door, and louver blades for opening and closing the opening, and both side walls of the opening are in the same direction with respect to the expected direction. The louver blade is rotatable around the vertical axis and the left and right end portions abut against the side wall to close the opening. The portion is overlapped with the side wall. The door of the present invention is used for both doors and sliding doors.

  The invention according to claim 2 of the present invention is characterized in that the louver blade rotates within the expected width of the door.

  The invention according to claim 3 of the present invention is characterized in that the opening is provided so as to be offset from the center of the door to one side in the direction of finding.

  The invention of claim 4 among the present invention is characterized in that the other side in the direction of finding is the door end side of the door body. In addition, one side of the finding direction corresponds to a hanging side when the door of the present invention is used as a door, and corresponds to the door bottom side when the door of the present invention is used as a sliding door.

  The invention according to claim 5 of the present invention is characterized in that both side walls of the opening portion are inclined toward one side in the finding direction from the outdoor side toward the indoor side.

  According to the first aspect of the present invention, the left and right end portions of the louver blades overlap the side walls of the opening, so that the line of sight from the front can be blocked. And since both the side walls of the opening are inclined with respect to the expected direction, even if the line of sight passes through the opening just before the door, the direction of the line of sight is inclined from the front. Therefore, since the central part of the room cannot be seen from the outside of the door, the line of sight from the outside can be blocked to some extent.

  According to the second aspect of the present invention, the louver blades rotate only within the expected width, and therefore, when used as a sliding door, the louver blades do not collide with the door pocket or the like.

  According to the invention of claim 3 of the present invention, since the opening is located at a position offset from the center of the door body, particularly when the door is installed near the center of the indoor wall (when used as a sliding sliding door, etc.) In many cases, the line of sight passing through the opening deviates further from the center of the room, so the effect of blocking the line of sight is high.

  According to the invention of claim 4 of the present invention, the louver blade is located on the hanging side (door bottom side), that is, when used as a door, it is located near the center of rotation and used as a sliding door. In this case, the door is located far from the door that collides with the vertical frame when closed, so that in any case, it is difficult to receive an impact when the door is closed, and rattling of the louver blade can be prevented.

  According to the invention of claim 5 of the present invention, when a wall surface is present on one side of the door that partitions the interior and exterior, even if an outside person approaches immediately before the outside of the door and the line of sight passes through the opening, Only the wall surface can be seen, and the line of sight from the outside can be almost blocked.

The 3rd Example of a door is shown, (a) is an outdoor side front view, (b) is explanatory drawing about interruption | blocking of the eyes | visual_axis from the outside.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiment shows a case where the present invention is used as an indoor door that partitions indoors and outdoors. As shown in FIGS. 1 to 3, the first embodiment of the door includes a door 1, an opening 2 provided in the door 1, and a louver blade 3 that opens and closes the opening 2. The left-right direction indicates the left-right direction in FIG.

  The door body 1 is configured by connecting a rectangular flat plate-like door end side (other side) door body 1a and a suspension base side (one side) door body 1b with a connecting member 21 with a gap therebetween. Both the door end side door body 1a and the suspension side door body 1b are flash panels in which surface materials are pasted on both sides of the frame material, but the door end side door body 1a is more than the suspension side door body 1b. The length in the direction of finding is long. The connecting member 21 is a square tube member, and is laid across the upper ends and the lower ends of the doors 1a and 1b.

  A vertical member 12 having a substantially Z-shaped horizontal cross section is attached to the hanging side surface 11a of the door side door body 1a and the door side surface 11b of the hanging side door body 1b. More specifically, as shown in FIG. 4, the vertical member 12 includes an intermediate surface 121 extending in the expected direction, a shielding surface 122 extending from one end of the intermediate surface 121 in a direction perpendicular to the intermediate surface 121, and the intermediate surface 121. A decorative surface 123 extending from the end in the opposite direction to the shielding surface 122 is provided, a tapping hole 125 is formed on the decorative surface 123 side of the intermediate surface 121, and a protrusion 127 from the decorative surface 123 side of the tapping hole 125. Is extended. On the other hand, a vertical groove 112 extending vertically is formed on the suspension side surface 11a of the door end side door body 1a and the door end side surface 11b of the suspension side door body 1b, and the protrusion 127 of the vertical member 12 is formed into the vertical groove. 112, the intermediate surface 121 is brought into contact with the hanging side surface 11a or the door end side surface 11b and fixed with an adhesive. The expected width of the intermediate surface 121 is substantially the same as the expected width of the doors 1a and 1b. In the door-end side door 1a, the decorative surface 123 comes into contact with the outdoor side surface, and the indoor side end of the hanging side surface 11a. The shielding surface 122 is extended toward the suspension base side. On the other hand, in the hanging side door body 1b, the decorative surface 123 abuts on the indoor side surface, and the shielding surface 122 extends from the outdoor side end of the door side surface 11b toward the door side. In addition, the finding width of the shielding surface 122 and the decorative surface 123 is the same, and the shielding surface 122 of one vertical member 12 and the decorative surface 123 of the other vertical member 12 are flush with each other. Further, in both the vertical members 12, a tight material 126 is provided at the tip of the shielding surface 122 (the outdoor side in the vertical member 12 of the door-end side door body 1a and the indoor side in the vertical member 12 of the suspension side door body 1b). It is provided. Further, a cover material 124 is provided from the front end of the shielding surface 122 to the base end of the decorative surface 123. Thus, the space surrounded by the vertical members 12 and the connecting members 21 is the opening 2, and the cover material 124 forms the wall surface of the inclined side wall 4 of the opening 2. It inclines toward the suspension side toward the indoor side. However, the cover material 124 is not essential, and in each of the doors 1a and 1b, either the outdoor side surface or the indoor side surface extends to the opening 2 side, or a member that extends to the opening 2 side (this embodiment) If a wall surface does not exist, it can be regarded as the inclined side wall 4. In addition, since the door end side door body 1a has a longer length in the direction of finding than the hanging base side door body 1b, the opening 2 is in a position offset toward the hanging base side.

  Further, as shown in FIG. 5, the connecting member 21 is fitted into the lateral grooves 13 formed on the upper and lower end surfaces of the doors 1 a and 1 b, and the tapping holes 125 of the doors 1 a and 1 b and the vertical member 12. It is screwed on. And since the protrusion 127 of the vertical member 12 is engage | inserted in the vertical groove 112, and it has fixed with the adhesive agent, both the door bodies 1a and 1b, the vertical member 12, and the connection material 21 are connected firmly. .

  Furthermore, a beam member 22 extending in the direction of finding is provided at the center of the opening 2 in the vertical direction, and the opening 2 is divided vertically. And the louver blade | wing 3 which opens and closes the opening part 2 is attached to each opening part 2 up and down. The louver blade 3 has a substantially rhombic cross section in the horizontal direction, and the length of one side is substantially the same as the width of the shield surface 122 and the decorative surface 123 of the vertical member 12. The length of the shorter diagonal (short axis) is substantially the same as the expected width of the doors 1a and 1b, and the end of the longer diagonal (long axis) (the end in the left-right direction) has a diagonal line. A fin piece 31 extending in the substantially extending direction is formed, and the length in the major axis direction including the fin piece 31 is longer than the width of the opening 2. Further, bearings 34 are provided at the upper and lower ends, and the louver blade 3 is rotatably mounted around the vertical axis by fitting the support shaft 32 fixed to the connecting member 21 and the beam member 22 into the upper and lower bearings 34. It is. More specifically, in the upper opening 2, the support shaft 32 is attached to the lower surface of the connecting member 21 and the upper surface of the beam member 22, and in the lower opening 2, the lower surface of the beam member 22 and the connecting member 21 are attached. A support shaft 32 is attached to the upper surface of each of the openings, and any of the support shafts 32 is attached to the center of the opening 2 in the direction of finding.

  As shown in FIG. 6, each support shaft 32 is formed with protrusions 33 projecting on both sides in the finding direction, and each bearing 34 has the louver blade 3 in an open state (the fin piece 31 is a tight material). The groove 35a that engages with the protrusion 33 and the louver blade 3 are closed (the fin piece 31 is in contact with the tight material 126). A groove 35b that engages with the protrusion 33 when in the contact state) is formed. The protrusion 33 engages with these grooves 35a and 35b, so that the rotation angle of the louver blade 3 is restricted, and the protrusion 33 rotates only within the expected width of the doors 1a and 1b.

  Further, as shown in FIG. 5, a cover plate 23 is attached to the outdoor side surface and the indoor side surface of the upper connecting member 21. The covering plate 23 extends downward and extends to a position below the upper end of the louver blade 3, and this extended portion is an extended piece 24. Therefore, the upper end of the louver blade 3 is sandwiched between the extending pieces 24 both indoors and outdoors. The extension piece 24 hides the gap between the louver blade 3 and the connecting member 21 and the support shaft 32 and the bearing 34. A covering plate 23 is attached to each of the lower connecting member 21 and the beam member 22, and the covering plate 23 of the lower connecting member 21 has an extending piece 24 extending upward. The plate 23 has extended pieces 24 extending upward and downward, and has the same function as that of the upper connecting member 21.

  With this configuration, the fin piece 31 of the louver blade 3 always overlaps the side wall 4 of the opening 2 when viewed from the expected direction. In order to close the opening 2, the louver blade 3 is rotated (clockwise in FIG. 1), and both fin pieces 31 are brought into contact with the tight members 126 on both side walls 4 of the opening 2. (FIG. 1 (b)). On the other hand, in order to open the opening 2, the louver blade 3 is rotated in the reverse direction (counterclockwise in FIG. 1), and both fin pieces 31 are separated from the tight material 126 on both side walls 4 of the opening 2. Good (FIG. 1 (a)). At this time, the projections 33 of the support shaft 32 are engaged with the grooves 35a and 35b of the bearing 34 of the louver blade 3, so that the rotation angle of the louver blade 3 is restricted and rotates only within the expected width of the doors 1a and 1b. In addition, the louver blade 3 is fixed in an open state or a closed state.

  In the door of this invention comprised in this way, the open / closed state of the opening part 2 can be switched only by pressing one fin piece 31 of the louver blade 3. FIG. At the time of closing, the fin piece 31 comes into contact with the tight material 126 on the side wall 4 of the opening 2 so that the operation sound is quiet and the sealing property in the closed state is high. On the other hand, at the time of opening, the fin pieces 31 at the left and right ends of the louver blade 3 overlap with the side walls 4 of the opening 2, so that the line of sight from the expected direction is always blocked. In addition, since both side walls 4 of the opening 2 are inclined with respect to the expected direction, even if the line of sight passes through the opening 2 close to the door 1, the direction of the line of sight is the direction inclined from the front. Become. And since the opening part 2 is offset and provided in the hanging origin side, as shown in FIG. 7, it approaches so that the indoor wall W may be located in the hanging origin side, just before the outdoor side of a door. Even if a line of sight passes through the opening 2, only the nearest wall surface can be seen, and the line of sight from the outside can be substantially blocked. In addition, since the horizontal cross-sectional shape of the louver blade 3 is rhombus and the side wall 4 is inclined, the side wall 4 and the side surface of the louver blade 3 opposed to the side wall 4 are substantially parallel when opened, so that air stays. There is no ventilation. Moreover, since the louver blade | wing 3 is located in the hanging origin side, it is hard to receive the impact at the time of a door closing, and the shakiness of the louver blade | wing 3 can be prevented. Furthermore, since the length of one side of the rhombic louver blade 3 is substantially the same as the width of the shield surface 122 and the decorative surface 123 of the vertical member 12, both doors 1a, 1a, It is a design with three lines in the vertical direction between 1b, and there is a sense of unity when viewed from inside or outside the door. In addition, since the shielding surface 122 is flush with the decorative surface 123, the uneven state in the expected direction is unified between the outdoor side and the indoor side. Furthermore, since the opening 2 is divided into upper and lower parts and louver blades 3 are respectively provided, the lower opening 2 is kept open even when the upper opening 2 through which the line of sight passes is mainly closed. Ventilation can be performed.

  Moreover, in FIG. 8, the case where it uses as an indoor sliding door which partitions indoors and outdoors as 2nd Example of the door of this invention is shown. In this case as well, the configuration is the same as that of the door, and there is an opening 2 between the door end side (the other side) door body 1a and the door bottom side (one side) door body 1b. A vertical member 12 is provided on the door butt side of the door tip side door body 1a and the door tip side surface of the door butt side door body 1b so that the side wall 4 of the opening 2 extends from the outdoor side to the indoor side. The opening 2 is vertically divided by a beam member 22 and louver blades 3 are attached to the upper and lower sides, respectively. And also in the sliding door of 2nd Example comprised in this way, the ventilation function and the function which interrupts | blocks a visual line are the same as that of the case of the door of 1st Example, Furthermore, the louver blade 3 has both door bodies 1a and 1b. Therefore, the louver blade 3 does not collide with the door pocket portion T.

  FIG. 9 shows a third embodiment of the door of the present invention. As in the second embodiment, the third embodiment is used as an indoor sliding door that partitions indoors and outdoors indoors. Here, one side corresponds to the door-end side, and the other side corresponds to the door-end side. One side) has an opening 2 between the door body 101a and the door bottom side (the other side) door body 101b, the opening 2 is offset to the door end side, and the door bottom side surface of the door end side door body 101a And the vertical member 12 is provided in the door side surface of the door butt side door body 101b, the side wall 4 of the opening part 2 inclines toward the door edge side toward the indoor side from the outdoor side, and the opening part 2 is a beam member. 22 is divided into upper and lower parts, and louver blades 3 are attached to the upper and lower parts respectively. The sliding door of the third embodiment configured as described above has a high effect of blocking the line of sight from the outside particularly when the indoor wall W is located on the door end side, and the ventilation function and the louver blade 3 do not collide with the door pocket portion T. The point is the same as in the second embodiment.

  The present invention is not limited to the above embodiment. This door is not limited to indoor use but can be used for various purposes such as a door for a front door and a sliding door. The door body may be a single plate other than the flash panel. Further, the opening may be not divided, or may be divided into three or more by providing two or more beam members. In that case, the louver blade also increases or decreases according to the number of openings. Further, the opening may be provided by forming a hole in one door. The shape of the louver blades is not limited to a rhombus with a horizontal cross-sectional shape, but may be any shape as long as it can abut against the side wall and close the opening, such as a rectangle or a parallelogram. May be. Further, more bearing grooves may be formed so that the louver blade can be fixed at an intermediate position between the open state and the closed state. Moreover, you may regulate a rotation angle by making a louver blade contact | abut to an extension piece irrespective of the groove | channel of a bearing, and the protrusion of a spindle. Furthermore, the vertical member may be screwed to the door body, and in that case, the head of the screw is hidden by the cover material, so the appearance is good.
