It is the attachment structure of a louver blade.

In one aspect, in each engagement portion, an engagement groove in a direction orthogonal to the longitudinal direction of the louver blade is formed in the outdoor portion and the indoor portion of the louver blade. The louver blade and the bent piece are engaged via an engaging groove formed in the louver blade.

When an engagement groove perpendicular to the longitudinal direction of the louver blade is formed on the louver blade side, it can be engaged even if an engagement groove is formed on the bent piece side or there is no engagement groove. However, in one aspect, the engagement groove is formed only in one of the outdoor side bent piece and the indoor side bent piece. Furthermore, in one aspect, one of the outdoor-side bent piece and the indoor-side bent piece has a larger bending dimension than the other, and only the bent piece having a larger bending dimension is involved. Grooves are formed. Moreover, you may weld the engaging part which engagement grooves engage.

In the mounting structure of the louver blade according to the present invention, the left and right side frames that have conventionally been attached to both ends of the louver blade by attaching the louver blade using a bent piece formed by bending the surface material of the door body. Is no longer necessary. That is, the left and right outdoor side bent pieces and the left and right indoor side bent pieces form the side surface of the opening for mounting the louver. Moreover, the upper surface and lower surface of the opening part for a louver attachment can be formed from a guillotine blade. Therefore, the conventional quadrilateral frame frame is not necessary, and the number of parts can be reduced.

According to the mounting structure of the louvered blades of the present invention, the louvered blades in the longitudinal direction of the louvered blades with respect to the bent piece formed by bending the outdoor side surface material of the door body and the indoor side surface material to the inside of the door body. Since it is engaged from the orthogonal direction, one surface material is engaged with one side of a plurality of galley blades, and then the other surface material is engaged with the other side of the galley blade with which one side is engaged. Can be made. Therefore, simultaneously with the step of attaching the other surface material to the one surface material, the louvered blade can be sandwiched and attached between the outdoor surface material and the indoor surface material, reducing the work process and improving workability. improves. Furthermore, in at least one engagement portion, the engagement grooves formed on both the bent piece and the louver blade are engaged with each other, so that in the engaged state, the position of the louver blade in the longitudinal direction with respect to the surface material It is easy to work without shifting.

Even if the engagement portion is welded with the surface blade engaged with one surface material, the gallery blade is temporarily fixed to the surface material by the engagement portion. Will improve. In addition, when welding is performed, welding can be performed at the engagement portion with the bent piece formed by bending the surface material inside the door body, so there is no need to weld with the surface material of the door body, and finishing after welding No work is required.

In the aspects described in claims 2, 3, and 4, the mounting operation of the louver blade and the bonding operation of the surface material can be performed more easily. A stable engagement state can be obtained by engaging the engagement grooves when engaging one side of the plurality of louvered blades with the bent piece of the one surface material. By enlarging the bending dimension of the bent piece in which the engaging groove is formed, the engaging portion can be enlarged, and the engaged state is further stabilized. And when engaging the bending piece formed in the other surface material simultaneously with the other side of the plurality of louvered blades with which one side is engaged, it is not necessary to form an engagement groove in the bending piece. Therefore, it is easy to align the other surface material.

Combined with the above-described effects, non-professionals can install the louver blade.

FIG. 1 is a front view of a door body, and the outdoor side and indoor side surface portions that form the finding surface of the door body 1 are respectively an outdoor side surface material 2 and an indoor side surface material 3 ( (Not shown in FIG. 1). An opening 4 (see FIG. 3A) is formed on the lower side of the surface of the door body 1 so as to penetrate the door body 1 in the thickness direction. When the body 1 is in the closed state, the indoor side and the outdoor side are communicated with each other through the louver 5. The louver 5 includes a plurality of louver blades 6 extending in parallel so as to span between the left and right side portions of the opening 4. The louver blade 6 is a steel long member formed by cutting out and bending a steel plate. The configuration of the louver blade 6 according to the present invention will be described with reference to FIGS. 2A and 2B. Throughout FIGS. 2A and 2B, common components of the louver blade are given the same reference numerals.

2A includes a plate-like surface portion 60 extending in the width direction of the opening 4. The dimension in the longitudinal direction of the surface portion 60 is substantially the same as the width dimension W of the opening 4 (see FIG. 4A), and the dimension in the short direction of the surface portion 60 is as follows when the louvered blade 6A is attached to the opening 4. The dimension is such that the louver blade 6A fits in the opening 4 (that is, the dimension such that the louver blade 6A does not protrude from the door body surface) (see FIG. 3A).

Engaging grooves 61, 62, 63, 64 that are notched in the direction orthogonal to the longitudinal direction of the surface portion 60 are formed at both longitudinal ends of the surface portion 60. Left and right end pieces 65 and 66 are integrally formed at both ends in the longitudinal direction of the surface portion 60 so as to be located outside the engaging grooves 61, 62, 63 and 64. The blades 6A are constituted by the pieces 65 and 66. The end edge 650 of the end piece 65 and the end edge 660 of the end piece 66 serve as end edges in the longitudinal direction of the entire louver blade 6A. In the end pieces 65 and 66, inclined guide edges 67 are formed at the openings of the engaging grooves 61, 62, 63 and 64. By forming the guide edge 67, the insertion of the outdoor bent pieces 20, 21 and the indoor bent pieces 30, 31 into the engaging grooves 61, 62, 63, 64 is facilitated. Moreover, the guide edge 67 ensures escape to the curved portion that can be formed on the inner side of the base end side of the outdoor-side bent pieces 20, 21 and the indoor-side bent pieces 30, 31 at the time of bending, These prevent interference.

In the illustrated example, the engagement grooves 61 and 62 are formed in the outdoor portion of the louver blade 6A, and the engagement grooves 63 and 64 are formed in the indoor portion of the louver blade 6A. The surface portion 60 includes long edges 68 and 69 extending in the longitudinal direction of the surface portion 60, and the louver blade 6 </ b> A is opened in a posture in which the surface portion 60 is inclined with the long edge 68 as the upper side and the long edge 69 as the lower side. It is attached to part 4 (FIG. 3A). The dimension between the upper edges 651 and 661 and the lower edges 652 and 662 of the end pieces 65 and 66 is smaller than the dimension between the long edges 68 and 69 of the surface part 60 (dimension in the short direction of the surface part 60). Thus, when the louver blade 6A is attached between the surface materials 2 and 3, the inner surfaces of the surface materials 2 and 3 and the end pieces 65 and 66 do not interfere with each other (see FIG. 4A).

The basic structure of the louver blade 6B shown in the lower part of FIG. 2A is as shown in FIG. 3C. The upper piece 680 extends vertically upward at the upper end of the inclined surface portion 60, and vertically downwards at the lower end. The configuration of the louver blade 6A is the same as that of the louver blade 6A except that a lower piece 690 extending in the direction is formed. The description of the louver blade 6A can be used for the description of the louver blade 6B.

FIG. 2B shows the gallery blades 6 </ b> C provided at the uppermost and lowermost positions of the gallery 5. The basic configuration of the louver blade 6C is that the louver blade 6A is formed except that vertical pieces 681, 691 extending vertically in the same direction from the upper and lower ends of the inclined surface portion 60 are formed. The description of the louver blade 6A can be used for the description of the louver blade 6C. The louver blade 6 </ b> C is attached in an upside down orientation depending on whether the louver blade 6 </ b> C is provided at the uppermost position of the gallery or the lowermost position of the gallery. As shown in FIG. 3A, in the uppermost louver blade 6C, the long vertical piece 691 is in contact with the inner surface of the outdoor surface material 2, and the short vertical piece 681 is in contact with the inner surface of the indoor surface material 3. The surface portion 60 forms the upper surface of the opening 4, and in the lowest louver blade 6 </ b> C, the long vertical piece 691 contacts the inner surface of the indoor surface material 3, and the short vertical piece 681 is the outdoor side. The surface 60 is in contact with the inner surface of the surface material 2, and the surface 60 forms the lower surface of the opening 4. Further, as is apparent from FIG. 3A, the horizontal dimension of the inclined surface portion 60 coincides with the dimension between the inner surfaces of the surface materials 2 and 3. Thus, the louver blade 6C also serves as a member that closes the upper part and the lower part of the opening 4.

As shown in FIG. 1, the opening 4 is formed in a square shape from an upper side 40, a lower side 41, a left side 42, and a right side 43 in a front view. The upper side 40 and the lower side 41 are formed from edges formed by cutting out the outdoor side surface material 2 and the indoor side surface material 3 (see FIG. 3A).

As shown to FIG. 4A, the left-right side part of the opening part 4 is the outdoor side bending pieces 20 and 21 formed by bending the outdoor-side surface material 2 toward the inside of a door body, and the indoor side surface, respectively. It is comprised from the indoor side bending pieces 30 and 31 formed by bending the material 3 toward the inside of a door body. The left side 42 of the opening 4 when viewed from the front of the door body is formed from a corner edge formed by the outdoor side surface portion formed from the outdoor surface material 2 and the outdoor bent piece 20, the indoor surface material 3. It consists of a corner edge formed by the indoor side surface portion and the indoor side bent piece 31, and the right side 43 is formed by the outdoor side surface portion formed by the outdoor side surface material 2 and the outdoor side bent piece 21. It consists of a corner edge formed by a corner edge, a room-side surface portion formed from the room-side surface material 3 and the room-side bent piece 30.

As for the outdoor side bending piece 20, the indoor side bending piece 30, and the outdoor side bending piece 21, and the indoor side bending piece 31, respectively, the front-end edges have opposed. In the illustrated embodiment, in particular, as shown in FIGS. 3A, 3B, 4A, and 4B, the outdoor bent piece 20 and the indoor bent piece 30, the outdoor bent piece 21 and the indoor bent piece 31, Bending dimensions are provided so that the edges abut against each other. That is, the sum of the bending dimension of the outdoor folding piece 20 (21) and the bending dimension of the indoor folding piece 30 (31) is substantially equal to the expected dimension (door thickness) D of the door body 1. . By doing so, the outdoor side bent piece 20 and the indoor side bent piece 30, the outdoor side bent piece 21 and the indoor side bent piece 31 constitute the left and right sides of the opening 4, and the opening 4 is the door. Communication with the internal space of the body 1 is prevented.

In the illustrated embodiment, the bending dimensions of the outdoor folding pieces 20 and 21 are set to be larger than the bending dimensions of the indoor folding pieces 30 and 31. As shown in FIGS. 3B and 5, a plurality of engagement grooves 200 are formed in the outdoor folded piece 20 at intervals in the height direction. Similarly, a plurality of engaging grooves (not shown) are also formed in the outdoor bent piece 21 at intervals in the height direction. The engagement groove 200 extends obliquely downward from the distal end edge of the outdoor folded piece 20 toward the base end side (outdoor surface portion), and the inclination angle of the engagement groove 200 is attached. It corresponds to the inclination angle of the surface portion 60 of the louver blade.

The louver blade 6 </ b> A is attached to the side of the opening 4, that is, the outdoor bent piece 20, the indoor bent piece 30, the outdoor bent piece 21, and the indoor bent piece 31 in an inclined posture. As shown in FIG. 5, the engagement groove 61 at the end of the louver blade 6A is inserted into the engagement groove 200 of the outdoor folded piece 20 from the direction perpendicular to the longitudinal direction of the louver blade 6A. And Similarly, the engagement groove 62 at the other end is inserted into the engagement groove of the outdoor bent piece 21 to be in an engaged state. Since there are a plurality of louver blades 6A, the plurality of louver blades 6A are similarly inserted into the outdoor folded pieces 20 and 21 to be in an engaged state.

A gallery blade 6C is attached to the top and bottom of the gallery 5. As shown in FIG. 6, the engagement groove 61 at the end of the louver blade 6 </ b> C is inserted into the engagement groove 200 of the outdoor bent piece 20 to be in an engaged state. Similarly, the engagement groove 62 at the other end is inserted into the engagement groove of the outdoor bent piece 21 to be in an engaged state.

By doing so, the louver blade 6A and the louver blade 6C are inserted from the direction perpendicular to the longitudinal direction of the louver blade into the outdoor bent pieces 20, 21 formed by bending the outdoor surface material 2. In this state, it is engaged and temporarily fixed. In both the louver blade 6 </ b> A and the louver blade 6 </ b> C, the engagement groove 61 engages with the engagement groove 200 of the outdoor folded piece 20, and the engagement groove 62 engages with the engagement groove of the outdoor bent piece 21. Therefore, in the engaged state, the positions of the louver blade 6A and the louver blade 6C are fixed and do not shift in the longitudinal direction. Further, since the outdoor bent piece 20 (21) has a large bending dimension, the size of the engagement groove 200 can be increased, and the engagement blade 20 has the ribs 6A and 6C. By engaging the engagement groove 61, the main portion in the short direction of the louvering blade 6A and the louvering blade 6C (in the illustrated example, as shown in FIGS. 3A and 3B, from 3/4 of the size in the short direction) Since 4/5) is engaged in the engagement groove 200 of the outdoor bent piece 20 (21), a stable engagement state can be obtained. From the viewpoint of fixing the position in the width direction of the opening 4 of the louvering blade 6A and the louvering blade 6C, at least one of the engagement grooves 61 is engaged with the engagement groove 200 of the one outdoor folding piece 20. It only has to match.

At this stage, welding is performed on each engaging portion formed by engaging the engaging grooves of the louver blade 6A and the louver blade 6C. Since each of the louver blade 6A and the louver blade 6C is in an engaged state with respect to the outdoor bent pieces 20, 21, it is necessary to fix the position of the louver blade 6A and the louver blade 6C by hand during welding. There is no workability. The welding operation may be performed each time the respective blades 6A and 6C are engaged, but after all the blades 6A and 6C are inserted and brought into the engaged state, the welding operations are performed collectively. Is more efficient. Welding is performed with respect to the engaging portion formed by engaging the engaging grooves of the louver blades. Since the engaging portion to be welded is located inside the door body, the welded portion is exposed to the outside. There is no exposure and no post-processing of welding is required.

In the state where the louvering blade 6A and the louvering blade 6C are fixed to the outdoor surface material 2, which is one surface material, the other surface is provided in each of the engagement grooves 63 and 64 on the indoor side of the louvering blade 6A and the louvering blade 6C. By inserting the indoor side bent pieces 30 and 31 of the indoor side surface material 3 which is a material from the direction orthogonal to the longitudinal direction of the louver blade 6A and the louver blade 6C, the louver blade 6A and the louver blade 6C become the outdoor surface. The material 2 and the indoor surface material 3 are sandwiched and fixed.

The indoor side bent pieces 30 and 31 of the indoor side surface material 3 are movable in the height direction of the door body 1 with respect to the respective engagement grooves 63 and 64 on the indoor side of the louver blade 6A and the louver blade 6C. Yes, since the groove portions are not engaged with each other, the plurality of pieces of the louvered blades 6A and the louvered blades 6C fixed to the outdoor surface material 2 are used for the indoor side bent pieces 30 and 31 of the indoor side surface material 3 once. Slide engagement is also easy.

When the door body 1 is manufactured, the outdoor surface material 2 and the indoor surface material 3 are fixed, so if the louver blade 6A, the louver blade 6C and the outdoor surface material 2 are fixed by welding, It is not necessary to weld the louver blade 6A, the louver blade 6C and the indoor surface material 3. In particular, in the illustrated embodiment, the main portions in the short direction of the louver blade 6A and the louver blade 6C (in the illustrated example, as shown in FIGS. 3A and 3B, the dimension in the short direction is 3/4 to 4/5). Is engaged in the engagement groove 200 of the outdoor bent piece 20 (21), so that the engaging portions of the louver blade 6A, the louver blade 6C and the outdoor bent piece 20 (21) are welded.
