Abstract
Description
[Technical Field]
[0001] The present disclosure relates to a louver structure that is applied to a louver ceiling, exterior louvers, etc. [Background technology]
[0002] Louver ceilings and exterior louvers are sometimes used inside buildings such as buildings (see, for example, Patent Document 1). In the ceiling louver mounting structure described in this document, multiple parallel-arranged ceiling louvers are connected to the lower parts of multiple beam members that are installed in a direction that intersects with the ceiling louvers. A rafter support member is installed between adjacent beam members in the longitudinal direction of the ceiling louvers. This rafter support member is connected to the top of the beam member via a connecting member and extends in the same direction as the ceiling louvers. The rafter support member is suspended by multiple hanging members installed on the ceiling.
[0003] Incidentally, inspection hatches are sometimes installed in ceilings. Therefore, inspection hatch structures in louvered ceilings have also been considered (see, for example, Patent Document 2). The louvered ceiling with an inspection hatch structure described in this document has parallel rafters made of steel members with concave cross sections arranged with the top surface open. Rafters are installed in the area of the inspection hatch in the louvered ceiling. Furthermore, gaps are provided between the rafters in the general area other than the inspection hatch so that they are positioned on the same line as the rafters. Then, protruding members protruding from both ends of the rafters in the area of the inspection hatch are positioned on the same line as the rafters, at the recessed corners of the steel members of the rafters in the general area.

[0005] However, the technology described in Patent Document 2 limits the shape of the joist. [Means for solving the problem]
[0006] A louver structure for solving the above problem comprises two fixed louver materials extending in a first direction and spaced apart in a second direction, a guide material extending in the second direction and disposed between the fixed louver materials, and a movable louver material extending in the first direction and sliding on the guide material along the second direction. [Effects of the Invention]
[0007] The present disclosure can provide an opening area between two fixed louver materials and achieve a well-fitting louver structure. [Brief explanation of the drawings]
[0008] [Figure 1] FIG. 2 is a perspective view of the louvered ceiling of the present embodiment. [Figure 2] FIG. 2 is a perspective view of the louvered ceiling of the present embodiment. [Figure 3] FIG. 2 is a plan view of the louvered ceiling of the present embodiment. [Figure 4] 1A and 1B are explanatory views of the main parts of the louver structure of this embodiment, in which (a) is a side view and (b) is a top view. [Figure 5] FIG. 10 is an explanatory diagram of a louver structure of another example. DETAILED DESCRIPTION OF THE INVENTION
[0009] An embodiment of a louver structure will be described below with reference to Figures 1 to 4. In this embodiment, it is assumed that an inspection hatch is provided as an opening facing the louver materials in a louver ceiling provided with a plurality of louver materials.
[0010] 1 and 2 are perspective views of the louvered ceiling A1 as seen from below. Fig. 1 shows the case where the inspection hatch 500 is closed, and Fig. 2 shows the case where the inspection hatch 500 is open. As shown in FIG. 1 , a joist support 10 is suspended from a ceiling slab C1 (structural material) by a hanging member (not shown). Below the joist support 10, louver materials 100 extend in the longitudinal direction (first direction v1). The louver materials 100 include fixed louver materials 110 spaced apart from each other and movable louver materials 120 extending in the first direction v1. The fixed louver materials 110 are fixed to the joist support 10. The movable louver materials 120 are not fixed to the joist support 10, and are configured to be movable relative to the joist support 10 and the fixed louver materials 110.
[0011] When viewed from a viewpoint opposite the inspection hatch 500 (viewed from below), the fixed louver materials 110 leave an area occupied by the inspection hatch 500 and are arranged at equal intervals in the width direction (second direction v2) of the fixed louver materials 110. In the louver structure, the louver materials 100 are arranged along a surface extending in the first direction v1 and the second direction v2. The inspection hatch 500 is arranged so as to face the surface extending in the first direction v1 and the second direction v2. The second direction v2 is perpendicular to the first direction v1.
[0012] Two fixed louver members 110 adjacent to the inspection hatch 500 in the second direction v2 support two guide members 200. The two guide members 200 are fixed to the two fixed louver members 110. When viewed from below, the two guide members 200 are aligned in the first direction v1 so as to leave the range of the inspection hatch 500 open.
[0013] The two fixed louver members 110 adjacent to the inspection hatch 500 in the first direction v1 are disposed outside the guide member 200 relative to the inspection hatch 500. Two movable louver members 120 are arranged below (in front of) the inspection hatch 500. The movable louver members 120 are arranged so as to be continuous in the first direction v1 from the two fixed louver members 110 adjacent to the inspection hatch 500 in the first direction v1. The movable louver members 120 are supported by guide members 200. The guide members 200 penetrate the movable louver members 120 in the second direction v2. The movable louver members 120 are guided in the sliding direction by the two guide members 200 so as to slide in the second direction v2, thereby enabling them to retreat from the area where the inspection hatch 500 is arranged.
[0014] As shown in Figure 2, when the inspection hatch 500 is opened, the movable louver material 120 is slid relative to the guide material 200 and moved in the second direction v2 to the vicinity of the fixed louver material 110 adjacent to the inspection hatch 500. This movement causes the movable louver material 120 to move away from the front (below) of the inspection hatch 500 in the second direction v2. An opening region is then formed in front (below) of the inspection hatch 500, which is a region where the spacing between adjacent louver materials 100 has widened in the second direction v2. The opening region is the region facing the inspection hatch 500 within the surface of the louver structure that extends in the first direction v1 and the second direction v2.
[0015] The inspection hatch 500 can be opened by rotating the lid 510 of the inspection hatch 500 toward the opening area around one end edge of the lid 510 in the second direction v2 as a rotation axis. The opened inspection hatch 500 can be closed by rotating the lid 510 from the opening area toward the ceiling slab C1. The movable louver material 120 can then be slid again to return the movable louver material 120 to its original position before movement so that the movable louver material 120 and the fixed louver material 110 are connected in the first direction v1, thereby positioning the movable louver material 120 again below the inspection hatch 500.
[0016] Fig. 3 is a plan view of the louver ceiling A1 viewed from below. In Fig. 3, the fixed louver material 110 arranged in the second direction v2 relative to the inspection hatch 500 is shown as the first fixed louver material 111, and the fixed louver material 110 arranged in the first direction v1 relative to the inspection hatch 500 is shown as the second fixed louver material 112. The second fixed louver material 112 is arranged at a predetermined position between the two first fixed louver materials 111, at the spacing of each louver material 100.
[0017] As shown in Figure 3, the two first fixed louver members 111 that sandwich the inspection hatch 500 in the second direction v2 have a gap between the inspection hatch 500 and the first fixed louver members 111 to allow for the placement of two movable louver members 120 (dotted lines in Figure 3). The guide member 200 is fixed to the two first fixed louver members 111 with fixing members 210 at a position away from the bottom of the inspection hatch 500.
[0018] The four second fixed louver materials 112 adjacent to the inspection hatch 500 in the first direction v1 have a gap between the inspection hatch 500 and the end of the second fixed louver material 112 to allow for the placement of one guide material 200.
[0019] Two movable louver members 120 are arranged below the inspection hatch 500, between the two first fixed louver members 111. The movable louver members 120 are supported by guide members 200 that are passed through the through holes 211. When viewed from below, the guide members 200 may be arranged alongside the joist support 10, or may be arranged so as to overlap the joist support 10. The diameter of the guide members 200 is smaller than the width of the joist support 10 and the width of the fixed louver members 110.
[0020] Both ends of the movable louver material 120 in the longitudinal direction (first direction v1) are separately positioned to the second fixed louver material 112 by the connecting portion 400. When the inspection hatch 500 is to be opened, the positioning by the connecting portion 400 is released, and the movable louver material 120 is moved to position P1 and retreated from below the inspection hatch 500. Here, an example is shown in which the two movable louver materials 120 are shifted to the left in the figure.
[0021] FIG. 4 shows the connecting portion 400, with FIG. 4(a) being a side view and FIG. 4(b) being a top view. As shown in FIG. 4(a), the fixed louver material 110 is fixed to the joist support 10 by a support material 11. The movable louver material 120 is not fixed to the support material 11 and is separated from the joist support 10. The movable louver material 120 has a through hole 211 through which the guide material 200 is inserted. The movable louver material 120 is supported by the guide material 200.
[0022] The through-hole 211 is arranged above the center in the height direction of the movable louver material 120. Because the diameter of the guide material 200 is small and the through-hole 211 is arranged in the upper part of the movable louver material 120, the guide material 200 is less visible when viewed from below, and the sense of unity created by the multiple louver materials 100 is enhanced.
[0023] The connecting portion 400 includes a locking member 401 and a shaft member 402. The shaft member 402 extends in the second direction v2 at the end of the second fixed louver member 112. The locking member 401 protrudes from the end of the second fixed louver member 112 toward the movable louver member 120. The locking member 401 has a thin plate shape that follows the side of the second fixed louver member 112. The surface of the locking member 401 may have the same pattern as the surface of the louver member 100. For example, if the louver member 100 is made of wood, the surface of the locking member 401 may have a wood grain pattern. The locking member 401 is rotatable around the shaft member 402.
[0024] The locking member 401 is positioned above the center in the height direction of the second fixed louver material 112. Because the locking member 401 has a thin plate shape and is positioned at the upper part of the second fixed louver material 112, the visibility of the locking member 401 when viewed from below is reduced, thereby improving the visibility of the louver material 100 in the louver structure. The surface of the locking member 401 has the same pattern as the surface of the louver material 100, giving the louver structure a sense of unity between the locking member 401 and the louver material 100.
[0025] As shown in FIG. 4(b), the guide material 200 is fixed to the fixed louver material 110 by fixing materials 210 such as nuts. The locking member 401 includes a top plate that fits along the top surface of the second fixed louver material 112, and two retaining plates that are fixed to the top plate and fit along the side surfaces of the second fixed louver material 112. The retaining plates sandwich the movable louver material 120 in the width direction, thereby positioning the movable louver material 120 relative to the fixed louver material 110. The positioning of the movable louver material 120 by the locking member 401 provides continuity in the first direction v1 between the movable louver material 120 and the second fixed louver material 112 to the louver structure.
[0026] 4(a), when separating the fixed louver material 110 and the movable louver material 120, the fixed louver material 110 and the movable louver material 120 are separated by pulling up the locking member 401. Then, by sliding the movable louver material 120 relative to the guide material 200, the movable louver material 120 is biased to the left.
[0027] (Action of this embodiment) The movable louver material 120 slides in the second direction v2 relative to the guide material 200 while being supported by the guide material 200. As a result, in a louver structure in which a plurality of louver materials 100 are arranged at predetermined intervals in the second direction v2, an opening area is formed in which the intervals between the louver materials 100 in the second direction v2 are widened.
[0028] (Effects of this embodiment) (1) In this embodiment, the movable louver element 120 is supported by a guide element 200 fixed to the fixed louver element 110 adjacent to the movable louver element 120. Because the slide mechanism is configured using louver elements 100 other than the movable louver element 120, a well-organized slide mechanism for the movable louver element 120 can be realized. The movable louver element 120 can then be slid to form an opening area. This allows an inspection hatch 500 to be provided on the back (ceiling side) of the movable louver element 120, and the lid portion 510 can be opened using this opening area.
[0029] (2) In this embodiment, multiple (two) movable louver members 120 are arranged below the inspection hatch 500. This makes it possible to slide the multiple movable louver members 120 to ensure the necessary opening area depending on the size of the inspection hatch 500.
[0030] (3) In this embodiment, the guide material 200 is fixed to the fixed louver materials 110 adjacent to both sides of the movable louver material 120, so that a sliding mechanism can be realized using the louver materials 100 arranged at equal intervals.
[0031] (4) In this embodiment, the guide material 200 is inserted into the movable louver material 120. This makes it possible to prevent the movable louver material 120 from falling off the guide material 200. Furthermore, as long as the structure of the movable louver material 120 allows the guide material 200 to be inserted into the movable louver material 120, no other special shape is required.
[0032] (5) In this embodiment, the movable louver material 120 is positioned and connected to the second fixed louver material 112 in the longitudinal direction at the connecting portion 400. This makes it possible to prevent the movable louver material 120 from shifting when the inspection hatch 500 is closed.
[0033] This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. In the above embodiment, the inspection hatch 500 is provided on the rear side of the movable louver material 120. However, it is not limited to the inspection hatch 500 as long as the opening area created by moving the movable louver material 120 can be used. For example, a display device, an operation panel, etc. may be disposed on the rear side of the movable louver material 120.
[0034] In the above embodiment, two movable louver members 120 are arranged below the inspection hatch 500. The number of movable louver members 120 is not limited to a plurality of louver members. As shown in FIG. 5, a single movable louver member 120 may be used.
[0035] In the above embodiment, the two movable louver members 120 are moved to one side to form an opening area below the inspection hatch 500. However, they may be slid to either side as long as an opening area can be formed.
[0036] In the above embodiment, the movable louver material 120 is connected to the second fixed louver material 112 in the longitudinal direction by the connecting portion 400. The structure of the connecting portion 400 is not limited as long as it can connect the movable louver material 120. The connecting portion 400 may be provided on the movable louver material 120.
[0037] For example, the end of the second fixed louver material 112 may have a slit extending in the first direction v1 at the center of the second fixed louver material 112 in the second direction v2. The slit of the second fixed louver material 112 opens on the top surface of the second fixed louver material 112 at the end of the second fixed louver material 112 and on the end surface in the first direction v1. When the movable louver material 120 is moved, the locking member 401 is accommodated in the slit of the second fixed louver material 112. When the movable louver material 120 is positioned on the second fixed louver material 112, the locking member 401 rotates about the shaft member 402 to protrude from the end surface of the second fixed louver material 112 in the first direction v1. The end of the movable louver material 120 has a slit extending in the first direction v1 at the center of the movable louver material 120 in the second direction v2. The slits of the movable louver material 120 open at the ends of the movable louver material 120 on the top surface of the movable louver material 120 and on the end surface in the first direction v1. The locking members 401 protruding from the second fixed louver material 112 are positioned within the slits of the movable louver material 120. This allows the movement of the movable louver material 120 in the second direction v2 to be releasably restricted by the second fixed louver material 112.
[0038] According to this modified example, the visibility of the locking member 401 is reduced to the extent that the locking member 401 is housed within the second fixed louver material 112 or the movable louver material 120. Furthermore, the multiple louver materials 100 give the louver structure a sense of unity.
[0039] Instead of rotating the locking member 401, the locking member 401 may be slid and protruded using the slit as a guide. The locking member 401 may be modified to have a columnar shape extending in the first direction v1 and housed within the second fixed louver material 112. The locking member 401 is configured to protrude from the end face of the second fixed louver material 112 in the first direction v1 or to be housed within the second fixed louver material 112, depending on the user's operation. In this case, the movable louver material 120 has holes for accommodating the locking member 401 protruding from the second fixed louver material 112. This also allows the movement of the movable louver material 120 in the second direction v2 to be releasably restricted by the second fixed louver material 112.
[0040] Furthermore, a protrusion may be provided on the end of the first fixed louver material 111 that is connected to the movable louver material 120, on the side opposite to the sliding direction of the movable louver material 120. For example, by providing a protrusion on the side opposite to the sliding direction, this protrusion can be used as a stopper for the movable louver material 120. When there are two movable louver materials 120, they are made to slide in opposite directions.
[0041] In the above embodiment, the louver structure is applied to a louvered ceiling A1. However, the present invention is not limited to the louvered ceiling A1. For example, the present invention may be applied to exterior louvers on a wall surface that are arranged horizontally or vertically on a vertical plane.
[0042] In the above embodiment, the extension direction of the louver material 100 and the extension direction of the guide material 200 are perpendicular to each other. As long as an opening area can be formed by moving the movable louver material 120 in the extension direction of the guide material 200, the extension direction of the louver material 100 and the extension direction of the guide material 200 may intersect at an angle other than perpendicular to each other.
[0043] The position where the guide material 200 penetrates the movable louver material 120 may be the center in the height direction of the movable louver material 120 or below the center. The guide material 200 may be fixed to the joist support 10. When the guide material 200 is fixed to the fixed louver material 110, restrictions on the configuration of the joist support 10 are reduced. When the guide material 200 is fixed to the joist support 10, restrictions on the configuration of the fixed louver material 110 adjacent to the movable louver material 120 are reduced.
[0044] A plurality of guide members 200 may pass through one end of the movable louver member 120. Alternatively, a plurality of guide members 200 may pass through each of both ends of the movable louver member 120. According to this modification, the guide members 200 are more likely to provide the strength to support the movable louver member 120.
[0045] When multiple guide members 200 pass through one end of the movable louver member 120, the multiple guide members 200 may be arranged vertically or horizontally. When multiple guide members 200 that pass through one end of the movable louver member 120 are arranged vertically, the multiple guide members 200 appear as if they were a single guide member 200 when the louvered ceiling is viewed from below. When multiple guide members 200 that pass through one end of the movable louver member 120 are arranged horizontally, it becomes easier for users of the louvered ceiling to understand the direction in which the movable louver member 120 can move.
[0046] In the above embodiment, the louver materials 100 are arranged in parallel. Alternatively, the present invention may be applied to a lattice in which louver materials are arranged in two directions. In this case, for example, a lattice consisting of two layers of first-direction louvers (vertical louvers) and second-direction louvers (horizontal louvers) is used. In this case, a sliding mechanism is formed by providing guide materials on both the vertical and horizontal louvers in the area that forms the opening area. Furthermore, the first-direction louvers may be pierced by the second-direction louvers, and the first-direction louvers may be used as guide materials for the second-direction louvers to slide.
[0047] Next, the technical ideas that can be understood from the above-described embodiment and other examples will be described below. (a) The louver structure according to any one of claims 1 to 4, characterized in that the fixed louver material is fixed to a joist support provided on a ceiling.
[0048] (b) The louver structure according to claim 3 or 4, characterized in that the opening area is provided in accordance with the arrangement of an inspection hatch. [Explanation of symbols]
