A portion (in this embodiment, an internal standing surface 44a of an inner extension 44 described later) is configured. Thereby, the guide rail 4 is engaged with the lower frame 5 for an illegal act of trying to deform the guide rail 4 by intentionally prying the lower component 4a of the guide rail 4 to the outdoor side, etc. The deformation and movement of the guide rail 4 can be suppressed, and consequently the crime prevention performance can be improved.

  Hereinafter, the details of each part will be described. As shown in FIG. 3, in the lower frame 5, a draining surface 5 b that protrudes from the indoor side to the outdoor side and forms a flat surface, and a protruding end portion of the draining surface 5 b upward. A rising fin 5a that protrudes toward the top is formed. The draining surface 5b is provided with a drain hole 5c penetrating in the vertical direction so as to discharge condensed water and the like captured by the draining surface 5b. The draining surface 5b may have an inclination such that the rising fin 5a side is slightly lower.

  Further, as shown in FIG. 3, the rising fin 5 a is formed at the end of the draining surface 5 b when the lower frame 5 is cast, or is formed by sheet metal processing or the like, and is integrated with the lower frame 5. It is supposed to be configured. Further, the rising dimension (height dimension) of the rising fin 5a from the draining surface 5b is to ensure the engagement with the guide rail 4, the strength to withstand the load received from the guide rail 4, It is designed as appropriate from the viewpoint of securing strength related to wind resistance (performance against deformation of the guide rail 4 due to strong wind). Furthermore, in addition to the viewpoint related to the strength, the rising dimension of the rising fin 5a is appropriately designed according to the design of the shutter device and the function of draining water.

In addition, an internal standing surface 44a that constitutes a surface that faces the guide rail exterior surface 42a substantially in parallel with the guide rail side surface 45c is provided. The internal standing surface 44a and the guide rail exterior surface 42a extend from the guide rail side surface 45c in the same direction.
Furthermore, a guide rail interior surface 46a that constitutes a surface facing the inner standing surface 44a substantially parallel to the inner standing surface 44a is provided in the middle of the inner standing surface 44a.
A space is secured between the internal standing surface 44a and the guide rail interior surface 46a, and this space functions as a guide groove portion 41 for guiding the shutter curtain.
Further, mohairs 47a and 47b are provided at the ends of the internal standing surface 44a and the guide rail interior surface 46a on the side opposite to the guide rail side surface 45c, respectively.

  Further, as shown in FIGS. 3, 4, and 6A, the lower component 4a of the guide rail 4 is disposed outside the rising fin 5a in the lateral width range of the guide rail 4. An outer extending portion 42 is configured (see FIG. 6A). The outer extending portion 42 has a guide rail exterior surface 42a to be disposed and a lowermost portion 42b is disposed in the vicinity of the lowermost portion of the rising fin 5a. The guide rail exterior surface 42a of the outer extending portion 42 constitutes the lower part of the above-described guide rail exterior surface 42a (see FIG. 4).

  Further, as shown in FIGS. 6A and 7, the outer extension portion 42 will be described in detail. The lower side of the guide rail side surface 45c in the lower component portion 4a of the guide rail 4 is opened in a side view. A substantially “U” -shaped cutout portion 46 is formed, and a portion disposed on the outdoor side of the cutout portion 46 is configured as the outer extension portion 42. Thus, the guide rail 4 straddles the rising fin 5a of the lower frame 5 by forming the cutout portion 46 to form the outer extending portion 42 (see FIG. 6A).

  Further, as shown in FIGS. 3 and 4, the lower component 4a of the guide rail 4 has an internal standing surface 44a that is disposed on the indoor side of the rising fin 5a and faces the rising fin 5a. The lowermost portion 44b is above the draining surface 5b of the lower frame 5 or an inner extending portion 44 is formed in contact with the draining surface 5b. The internal standing surface 44a of the inner extending portion 44 constitutes the lower part of the above-described internal standing surface 44a (see FIG. 6).

  Further, as shown in FIGS. 6A and 7, the inner extending portion 44 will be described. The lower side of the guide rail side surface 45c of the lower component portion 4a of the guide rail 4 is opened in a side view as shown in FIG. A U-shaped notch 46 is formed, and a portion on the indoor side of the notch 46 is configured as an inner extension 44.

  Then, as shown in FIGS. 6A and 7, with the above configuration, the inner standing surface 44a faces the inner standing surface 5d of the rising fin 5a, and the lower component portion 4a of the guide rail 4 is placed in the chamber. When a load to be deformed outward is generated, the inner standing surface 44a comes into contact with the inner standing surface 5d of the rising fin 5a. That is, the internal standing surface 44 a functions as an engaging portion with respect to the lower frame 5. As a result, the lower component 4a of the guide rail 4 is engaged with the lower frame 5, and the rigidity of the lower frame 5 that is firmly fixed to the building frame is prevented from being deformed or moved to the outdoor side of the guide rail 4. It can be regulated by.

  As shown in FIGS. 6A, 6B and 7, a cap 48 for covering the lower end surface of the outer extending portion 42 is provided at the notch portion 46 from the lower side of the guide rail 4. It is going to be inserted. Further, the cap 48 is provided with a drain hole 49 penetrating in the vertical direction, thereby discharging condensed water or the like between the internal standing surface 44a and the guide rail exterior surface 42a downward. It is desirable to be able to do it.

  As described above, in the present embodiment, as shown in FIGS. 3 and 6A and 6B, the guide rail 4 is disposed on the indoor side of the rising fin 5 a configured on the lower frame 5. An inner extending portion 44 and an outer extending portion 42 disposed on the outdoor side of the rising fin 5a, and engaging the inner extending portion 44 with the rising fin 5a, The inner extension portion 44 constitutes an engagement portion for the lower frame 5.

  As described above, the engaging portion is constituted by the internal standing surface 44a, and the guide rail 4 is engaged with the lower frame 5 by the engaging portion, so that the lower portion is firmly fixed to the building frame. The deformation and movement of the guide rail 4 can be restricted by the rigidity of the frame 5, and the crime prevention performance and wind resistance performance can be improved.

  In addition, since the guide rail 4 straddles the rising fin 5 a and the rising fin 5 a is covered and hidden by the outer extending portion 42, the engagement position between the guide rail 4 and the lower frame 5 is hidden by the guide rail 4. Thereby, the design property by the guide rail exterior surface 42a is securable.

  And the design of the guide rail end portion with the guide rail exterior surface 42a in this way is a series of seamless designs compared to the conventional configuration in which the exterior material of another member is provided at the end portion. It becomes possible to exhibit excellent aesthetics. For example, in a guide rail, when an exterior is configured with an aluminum material feeling and a design that exhibits an aesthetic appearance is formed, the seamless design exhibits an excellent aesthetic appearance. Moreover, since another member is not required for ensuring the design properties, a configuration with a small number of parts can be obtained, and an advantageous configuration can be realized in terms of cost and construction man-hours.

  In Example 1, the guide rail and the lower frame in the above-described embodiment are provided with a reinforcing member that reinforces the inner extension 44 on the guide rail side, thereby further deforming the guide rail. By preventing it reliably, the crime prevention performance is further improved.

The reinforcing member 51 that contacts the inner standing surface 5d of the fin 5a is provided, and the deformation of the guide rail 4 is more reliably prevented by the reinforcing member 51.

  Further, as shown in FIGS. 8 and 9A, the reinforcing member 51 is formed by bending a plate material whose plate width is substantially the same as the left and right width of the guide rail 4 into a substantially “U” shape. It has the structure which has the part 51a, the upper-plate part 51b, and the inner-plate part 51c.

  Further, as shown in FIGS. 8 and 9A, in the first embodiment, the guide rail 4 is made of an aluminum material and the reinforcing member 51 is made of a stainless steel material, which is relatively deformed with respect to an external load. The structure which reinforces the easy guide rail 4 with the reinforcing member 51 which is comparatively hard to deform | transform is implement | achieved. The material of the reinforcing member 51 is not particularly limited to stainless steel, but it is preferable to use a material exhibiting high rigidity.

  Further, as shown in FIGS. 8 and 9A, the reinforcing member 51 is attached so as to cover the cap 48. Here, the cap 48 includes an upper and lower plate portion 48a that constitutes a plate-like portion in the vertical direction in the installed state, and an upper portion of the upper and lower plate portion 48a that protrudes indoors from the indoor side surface 48b of the upper and lower plate portion 48a. A protrusion 48c is provided. The inner plate portion 51c of the reinforcing member 51 is opposed to the indoor side surface 48b of the cap 48, and the outer plate portion 51a of the reinforcing member 51 is brought into contact with the outdoor side surface 48d of the upper and lower plate portions 48a. Reinforcing member 51 is attached. As shown in FIG. 8, a concave portion 48f is provided in the upper projecting portion 48c of the cap 48, and a part of the inner plate portion 51c is accommodated in the concave portion 48f, whereby the cap 48 and the reinforcing member 51 are laterally disposed. The direction is not misaligned.

  As described above, as shown in FIG. 9A, the space 52 sandwiched between the two surfaces is formed between the indoor side surface 48b of the cap 48 and the outdoor side surface 51d of the inner plate portion 51c of the reinforcing member 51. It is formed. Then, as shown in FIG. 9B, the rising fin 5a is inserted into the space 52.

  Further, the cap 48 to which the reinforcing member 51 is attached as described above is inserted from below into the notch 46 of the guide rail 4 as shown in FIG. 8 and FIG. It is attached to 4a. With this configuration, the internal standing surface 44a of the guide rail 4 and the inner plate portion 51c of the reinforcing member 51 are integrated to form a single plate material, and the guide rail 4 is reinforced by the reinforcing member 51, The rigidity is improved.

  When the load which deform | transforms as mentioned above and deform | transforms the lower structure part 4a of the guide rail 4 to the outdoor side arises, as shown in FIG.9 (b), the outdoor side surface 51d of the said reinforcement member 51 is the rising fin 5a. It will be in contact with the inner standing surface 5d. Thereby, the lower component part 4a (internal standing surface 44a) of the guide rail 4 is engaged with the lower frame 5, and the deformation and movement of the guide rail 4 to the outdoor side are firmly fixed to the building frame. The lower frame 5 can be regulated by the rigidity of the lower frame 5. Furthermore, since the rigidity of the inner extending portion 44 of the guide rail 4 is improved by the reinforcing member 51, the crime prevention performance and wind resistance performance of the above-described embodiment can be further improved. In addition, since the reinforcing member 51 is accommodated in the guide rail 4, the above-described designability is not impaired.

  In addition to the form of the reinforcing member 51 described above, for example, a reinforcing member provided with a portion that reinforces the internal standing surface 44a on the indoor side of the internal standing surface 44a, or an internal standing surface It can be considered that the reinforcing member is provided with two reinforcing surfaces sandwiching 44a from both sides. That is, it is only necessary to improve the rigidity of the lower component part 4a, and the present invention is not limited to the above form.

  In the second embodiment, as shown in FIG. 10, the lower component 61 of the guide rail 4 is arranged on the indoor side of the rising fin 5a of the lower frame 5, and the guide rail exterior surface 42a of the lower component 61 is provided.

Is provided with a reinforcing member 65 which is fixed to the lower frame 5 side and engages with the lower component 61, and the reinforcing member 65 is disposed in a range below the uppermost position of the rising fin 5a. It is set as a structure.

  In the second embodiment, as shown in FIG. 10, the reinforcing member 65 is applied to the lower plate surface portion 65a applied to the draining surface 5b of the lower frame 5 and the inner standing surface 5d of the rising fin 5a. From the standing portion 65b, a plate member having a substantially “L” shape in cross section is formed. Further, the plate width of the reinforcing member 65 is substantially the same as the lateral width of the guide rail 4.

  As shown in FIG. 10, the uppermost position 65c of the standing portion 65b of the reinforcing member 65 is configured to be equal to or lower than the uppermost position 5e of the rising fin 5a, and when viewed from the outdoor side, the rising fin 5a. Therefore, the reinforcing member 65 is hidden. The lower plate surface portion 65a is fixed to the draining surface 5b by an adhesive or a fixing means such as a screw.

  When the load which deform | transforms as mentioned above and deform | transforms the lower structure part 61 of the guide rail 4 to the outdoor side arises, the guide rail exterior surface 42a of the said lower structure part 61 is the erection part 65b of the said reinforcement member 65. It abuts on the inner standing surface 65d. As a result, the guide rail 4 is engaged with the lower frame 5, and deformation and movement of the guide rail 4 toward the outdoor side can be restricted by the rigidity of the lower frame 5 that is firmly fixed to the building frame. . Furthermore, since the rigidity of the lower frame 5 (the rising fin 5a) is improved by the reinforcing member 65, the above-described crime prevention performance and wind resistance performance can be further improved. In addition, since the reinforcing member 65 is hidden by the rising fins 5a, the above-described designability is not impaired.

In other words, the rising fin 5 a of the lower frame 5 is disposed between the engaging portion 70 a and the guide rail 4. The plate width of the reinforcing member 70 is substantially the same as the lateral width of the guide rail 4.

  Further, as shown in FIG. 11, the engaging portion 70a is formed with respect to the rising fin 5a, and the fixing portion 70b is formed with respect to the guide rail exterior surface 42a. It is supposed to be fixed by fixing means.

The material of the reinforcing member 70 is not particularly limited to stainless steel, but is preferably composed of a material that exhibits high rigidity.

  As described above, as shown in FIG. 11, when a load that deforms the lower component 61 of the guide rail 4 to the outdoor side is generated, the guide rail exterior surface 42 a of the lower component 61 has the rising fin 5 a. It comes in contact with the inner standing surface 5d. Further, the guide rail 4 is engaged with the lower frame 5 via the reinforcing member 70.

  As described above, in addition to the engagement between the guide rail exterior surface 42a of the lower component 61 and the rising fin 5a, the guide rail 4 is engaged with the lower frame 5 via the reinforcing member 70. Thus, when a load that intentionally pry the guide rail 4 to the outdoor side is generated, the deformation or movement of the guide rail 4 to the outdoor side is caused by the rigidity of the lower frame 5 that is firmly fixed to the building frame. It can be regulated. Furthermore, since the rigidity of the lower frame 5 (rise fin 5a) is improved by the reinforcing member 70, the above-described crime prevention performance and wind resistance performance can be further improved.

  As an application example of the present invention, it can be widely applied as a technique for improving the crime prevention performance and wind resistance performance of a shutter device for closing a building opening.
