The shutter device 1 includes a shutter case 2 provided on a ceiling portion of a housing opening, the shutter A winding drum 3 rotatably mounted in the case 2, a shutter curtain 4 wound around the winding drum 3, and guide devices 5 provided on both left and right inner surfaces of the housing opening, and the like. As the take-up drum rotates forward and backward, the shutter curtain 4 is fed out to the take-up drum 3 and is taken up and down to be guided to the guide rail 5 to open and close the opening. Both are conventional.
In this embodiment, the shutter device is provided with the electric opening / closing device E. However, the shutter curtain may be manually driven up and down. The opening / closing device is not limited to a shutter device provided with a shutter curtain. For example, a conventionally known opening / closing body such as a grill shutter or a plate-shaped opening / closing body (opening / closing door, panel body) is raised or lowered. It may be.

The shutter curtain 4 is fixed to a flat plate portion 4e of an inverted T-shaped seat plate 4b having a plate-like slat 4a interlocked in the vertical direction and a bottom end of the shutter curtain 4 via screws 4f. And 4 g of a panel portion (or a plate body, which corresponds to the “waterproof structure portion” of the present invention). Thus, by attaching the panel part 4g to the seat plate 4b, the panel part 4g can be retrofitted, and even the existing shutter curtain 4 can be implemented. The thickness of the panel portion 4g is set so that the left and right ends enter the guide rail 5 and are guided up and down, and when the shutter curtain 4 is fully opened, the thickness is entered from the squeeze opening 2a provided on the lower surface of the shutter case 2. Further, the vertical length (height) of the panel portion 4g is set to a length that stops when the shutter curtain 4 is fully opened and stopped before being wound around the winding drum 3. In the fully open state, the lower end edge of the panel portion 4g is set to be positioned at the lower end edge position of the squeeze port 2a or slightly above and below this position. In such a position setting, when the shutter device 1 is electrically operated, the stop position can be controlled using a conventionally known position detection switch (sensor) or the like.
Incidentally, when the seat board part 4a is comprised with a panel body, it can comprise so that an inside may be reinforced with a frame material.

The guide rail 5 has a hat-shaped cross section in the present embodiment, and a pressing tool 6 in which the present invention is implemented is provided at the lower end portion of the groove bottom portion 5 a of the guide rail 5.
The pressing tool 6 is configured to include a flat substrate 6a that is long in the vertical direction and has a width in the front-rear direction, the left and right outer surfaces of the substrate 6a abut against the groove bottom 5a, and the lower edge of the substrate 6a is the floor. The upper end portion is fixed to the groove bottom portion 5a via the screw 6b while being in contact with the surface. Incidentally, the facing portion (contact portion) between the groove bottom 5a and the substrate 6a is waterproofed using a waterproof material such as a waterproof putty or an ept sealer (not shown). The substrate 6a is narrower than the groove width of the guide groove 5b of the guide rail 5, and can be retrofitted to the existing guide rail 5.

The pressing body 7 is provided on the inner surface side of the substrate 6a of the pressing tool in a state in which the pressing body 7 protrudes inward in the left-right direction. The first pressing portion 7a that is long in the vertical direction so that the lower end reaches the floor surface, and protrudes inward in the left-right direction from the lower end of the first pressing portion 7a and on the floor surface. The first pressing portion 7a is formed in a triangular prism shape having a substantially square-shaped projecting portion 7c. As the portion 7c is lowered, the front and rear skirt portions 7d are narrowed to form a first cone 7g having a cone shape that reaches the substrate 6a through the first vertex 7e.
The second pressing portion 7b has a triangular shape as well, but the ridge portion 7c becomes lower toward the inner side in the left-right direction and the front and rear hem portion 7d becomes narrower, and the cone shape reaches the floor surface F through the second vertex 7f. It becomes the second cone 7h. The second apex 7f, which is the inner end in the left-right direction of the second pressing portion 7b, is dimensioned so as not to protrude inward in the left-right direction from the groove opening end 5b of the guide rail 5 (contains in the guide groove 5b). . Incidentally, the space between the second pressing portion 7b and the floor surface F is waterproofed using a waterproof material such as a waterproof putty or an ept sealer (not shown). As a matter of course, the second pressing portion 7b may be configured such that the portion on the substrate 6a side has a triangular prism shape and the tip side portion has a cone shape like the first pressing portion 7a.

On the other hand, 8 is a waterproof material made of a rubber elastic material, and the waterproof material 8 has a solid shape (may be hollow) and has a bowl shape in cross section, and the flat bottom surface 8a has the above-mentioned shape. Although it attaches to the left-right direction side surface 4c and the bottom face 4d of the panel part 4g, in this Embodiment, it attaches by adhesion | attachment. The attachment of the waterproof material 8 to the panel portion 4g is not limited to adhesion. For example, the panel portion 4g is provided with a dovetail-shaped locking groove having a wide back side, and the locking protrusion provided on the waterproof material bottom surface 8a in the locking groove. The strip may be forcibly fitted and locked, and generally known general-purpose attachment techniques can be employed.
The waterproof material 8 is sufficient if the side surface portion 8b attached to the left and right side surfaces 4c of the panel portion 4g has a length corresponding to the first pressing portion 7a, and the bottom surface portion 8c attached to the bottom surface 4d is a panel. It is provided over the entire width of the bottom surface 4d in the left-right direction.
Incidentally, it is preferable that the waterproof material 8 is a seamless one-piece for ensuring waterproofness. However, in the case where there is a seam, there is a problem if the waterproofness is secured by bonding the seam or the like. It can be adopted without.

  When the shutter curtain 4 descends and the lower end portion of the waterproof side surface portion 8b reaches the first pressing portion 7a, the arcuate head portion 8d has the deepest contact portion of the ridge portion 7c of the first pressing portion 7a. When the shutter curtain 4 is gradually lowered and fully closed, the weight of the shutter curtain 4 is received and the guide rail is forced. 5, the bottom surface portion 8c of the portion corresponding to the second pressing portion 7b is forcibly pressed so that the ridge 7c contact portion of the second pressing portion 7b is in the deepest state, and is elastically deformed into a concave shape, The other bottom surface portion 8c is abutted against the floor surface F and crushed, and thus is configured to maintain waterproofness.

  In this case, the upper end portion of the first pressing portion 7a becomes the first cone 7g that reaches the substrate 6a through the first apex 7e with the crest portion 7c being lowered toward the upper side and the front and rear skirt portion 7d being narrowed. Therefore, when the side surface portion 8b is pressed and crushed by the first pressing portion 7a, the side surface portion 8b is crushed so as to gradually become deeper from the head portion 8d in the process of lowering the shutter curtain 4, Smooth elastic deformation will be performed, and sudden elastic deformation will not be forced as in the case where there is no first cone 7g, and the side surface of the part moved below the first cone 7g. The portion 8b is crushed in a state where the ridge portion 7c is deepest, and high waterproofness is exhibited.

  Further, with respect to the bottom surface portion 8c of the waterproof material, in a state where the weight of the fully closed shutter curtain 4 is received, a portion on the corner side with the side surface portion 8b is deeply crushed by the second cone 7h, and high waterproofness is exhibited. Then, the portion closer to the second vertex 7f of the bottom surface portion 8c has a smaller amount of crushing by the ridge portion 7c, but as with the intermediate portion without the second pressing portion 7b, the elastic deformation due to the dead weight of the fully closed shutter curtain 4 Thus, a sufficient waterproof function can be exhibited.

  In the present embodiment configured as described, the waterproof material 8 is provided on the left and right side surfaces 4c and the bottom surface 4d of the panel portion 4g, and the waterproof material 8 is crushed to exhibit a waterproof function. A pressing tool 6 is formed by a first pressing portion 7a and a second pressing portion 7b that press the side surface portion of the waterproof material 8 that fits in the guide groove 5b of the guide rail 5, and on the floor surface between the guide rails 5 The intermediate portion of the floor surface F without the pressing portion can exhibit a sufficient waterproof function due to the elastic deformation of the waterproof material 8 that receives the weight of the shutter curtain 4, but due to the weight of the shutter curtain 4. About the corner part of the panel part 4g which is hard to receive a waterproof function, since the waterproof material 8 is positively crushed and elastically deformed by the first and second pressing bodies 7a and 7b, a high waterproof function can be exhibited. , It is possible to prevent the ingress of water from the weather side.

  Moreover, in this case, since the second pressing body 7b that waterproofs the floor surface F is set to fit in the guide rail 5, the floor surface F between the left and right guide rails 5 remains flat and the opening portion There is no hindrance to getting in and out.

  In addition, since the first pressing body 7 a is provided with the first cone 7 g on the upper end side, the waterproof side surface portion 8 b provided on the side surface 4 c of the panel portion 4 g is changed to the first when the shutter curtain 4 is closed. When pressed by the pressing portion 7a, it is guided to be gradually deepened by the first cone 4g, so that sudden pressure deformation may occur as in the case where there is no first cone 4g. Therefore, the waterproof side surface portion 8b can be protected.

  Moreover, about the 2nd press part 7b, since it becomes the 2nd cone 7h set so that the protrusion end side (2nd vertex 7f side) may become gradually short and reach the floor F, it is in the protrusion end side. The waterproof function is surely ensured.

  The pressing tool 6 provided with the first and second pressing portions 7a and 7b exhibiting such an excellent waterproof function is provided on the substrate 6a. The substrate 6a is a groove of the guide rail 5. Since the width is smaller than the width, the existing shutter device 1 can be inserted and incorporated into the guide rail 5. In this case, in the present embodiment, since the substrate 6a is only fixed to the groove bottom portion 5a with the screw 6b at one upper end portion, the waterproof function at the corner portion of the pressing body 7 is not impaired. However, in this case, a bent portion 7i is formed by bending the upper portion of the first pyramid 7g of the substrate 6a toward the groove bottom of the guide rail 5, and the substrate 6a is moved in this state. When the penetrated screw 6b is screwed into the groove bottom portion 5a, the bent portion 7i is deformed linearly, whereby the first pressing body 7a contacts the groove bottom portion 5a in a watertight manner. At the same time, the second pressing body 7b also comes into contact with the floor surface F in a watertight manner, and can be attached without rattling. Of course, it goes without saying that a watertight material is provided on the back surfaces of the substrate 6a and the second pressing body 7b to ensure further watertightness.

Further, in this case, the panel portion 4g at the lower end of the shutter curtain 4 is a waterproof structure portion made of a panel material or a plate material, etc., but the thickness of the panel portion 4g is set to a size setting that is squeezed into the shutter case squeezing portion 2a. Therefore, when the shutter curtain 4 is fully opened, the panel portion 4g enters the shutter case 2, so that the panel portion 4g does not hang down from the lintel portion and the appearance is not impaired. Of course, the lower end portion of the panel portion 4g may be protruded from the lintel portion.
In addition, the panel portion 4g encased in the shutter case 2 is dimensioned so that the upper end is not entrained in the take-up drum 3, so that the winding posture is not impaired.

  In addition, as the shape of the ridge part 7c formed in the pressing body 7, the sharper it becomes, the more easily the waterproof material 8 is scratched. Shape) or an arc shape. For example, an arc shape as in the second embodiment of FIG. 9A, a chamfered surface as in the third embodiment of FIG. 9B, and the like ( As in the fourth embodiment of (C), it is possible to make an appropriate shape such as one having two ridges 7c in parallel.

  The present invention can be used as a waterproof device for an architectural shutter device.
