SUMMARY OF THE INVENTION A waterproof shutter according to the present invention is made of an aluminum form material, and has an opening defined as a part of a door by an upper frame, a lower frame, and both side frames. The frame 1 is made of a “U” -shaped form material in which the inner wall portion 11 hangs down from the outer wall portion 12, and the lower frame 2 is made up of the inner wall portion where the outer wall portion 22 is located higher than the inner wall portion 21. The upper frame 1 is formed of a form material having a water hanging wall portion 23 having a continuous water hanging gradient at an upper edge of the portion 21.
A blind-like oscillating blade 4 is provided between the lower frame 2 and the lower frame 2 so that the blind-like oscillating blade 4 is pivotally mounted in parallel to the two frames 1 and 2 so as to be freely swingable. An outer wing portion 42 extending upward on the outer edge and an inner wing portion 43 extending downward on the inner edge are made of a plate-shaped form material bent and formed so as to be parallel to each other. The rotor blades 4 are set such that the wing tip of the outer wing portion 12 is located higher than the lower edge position of the inner wall portion 11 of the upper frame 1 and lower than the lower edge position of the outer wall portion 12 at the shaft erection position. , And the inner wing 1
3 is provided in the structure of the ventilation window set so that the wing tip is located at a position higher than the upper edge position of the inner wall portion 21 of the lower frame 2 and lower than the upper edge position of the outer wall portion 22. It is.

That is, the waterproof shutter of the present invention comprises a projecting shaft 52 of a shaft member 5 fixed to both ends of the blind-like swinging blade 4.
Are mounted on the bearing member 6 made of a hard synthetic resin having appropriate elasticity and fixed on both sides of the opening, and a plurality of click locking recesses are formed in a leaf spring structure 66 formed integrally with the bearing member 6 in a thin-walled shape. A click locking mechanism 64 which has a structure in which the locking arms 53 projecting from the shaft member 5 are selectively elastically engaged with the click locking recesses 67, 68, 69. The gist is that the blind-like swinging blade 4 is click-held in a predetermined posture such as an “open” position or a “closed” position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a waterproof shutter according to the present invention will be described below with reference to FIGS. The present embodiment shows a waterproof shutter made of an aluminum form material formed on a bathroom door a. Reference numeral 1 denotes an upper frame, reference numeral 2 denotes a lower frame, and reference numeral 3 denotes a side frame. It has a width substantially equal to.

Further, IN indicates the inside of the door a and OUT indicates the outside. The upper frame 1 is a "U" -shaped frame material in which the inner wall portion 11 hangs down from the outer wall portion 12, and the lower frame 2 is Conversely, the outer wall portion 22 is located at a higher position than the inner wall portion 21, and is a formwork material having a water hanging wall portion 23 having a water hanging gradient that is continuous from the middle of the outer wall portion 22 to the upper edge of the inner wall portion 21.

The upper frame 1 and the lower frame 2 are erected in parallel between the side frames 3 and 3 to constitute a rectangular frame, and the blind-like swinging blades 4 Are pivotally mounted in parallel with the two frames 1 and 2 so as to be swingable. The blind-like oscillating blade 4 is provided on the outer edge of a central wing portion 41 having substantially the same width as each frame material.
An outer wing portion 42 extending upward and an inner wing portion 43 extending downward on the inner edge are made of a plate-shaped form material bent so as to be parallel to each other. It is pivotally mounted on both side frames 3 and 3 via provided shaft members 5 and 5 which will be described later.

The blind-like oscillating blade 4 has a wing tip of an outer wing portion 12 at a shaft erection position where an inner wing portion of the upper frame 1 is provided.
1 is set at a position higher than the lower edge position of the outer wall portion 12 and lower than the lower edge position of the outer wall portion 12, and the wing tip of the inner wing portion 13 is higher than the upper edge position of the inner wall portion 21 of the lower frame 2. Is set at a position lower than the upper edge position of the outer wall portion 22.

The two shaft members 5 and 5 have a symmetrical structure, and are mounted on bearing members 6 and 6 having a symmetrical structure fixed to the side frames 3 and 3 at swing end positions within a predetermined angle range. The shaft member 5 and the bearing member 6 are formed of a hard synthetic resin having appropriate elasticity.

The shaft member 5 has a protruding shaft 52 extending laterally from a fitting base portion 51 fitted and fixed to the end of the central wing portion 41 of the blind-like swinging blade 4. The locking arm 53 projects from the base in the orthogonal direction. Reference numeral 54 denotes a blade swing operation knob formed at a corner from the fitting base 51 to the center wing portion 41 and the inner wing portion 43 of the blind-like swing blade 4.

In the bearing member 6, a shaft hole 62 for rotatably mounting the protruding shaft 52 is formed substantially at the center of a plate-shaped base portion 61 which is fitted and engaged with the side frame 3. , A click locking mechanism 64 is integrally formed so as to face the end of the locking arm 53. The click locking mechanism 6
Reference numeral 4 denotes a plate spring structure 66 having a pair of click locking recesses 67 and 68 having a continuous sliding surface between both ends of the arcuate support 65, and is stretched by the elasticity of a synthetic resin as a molding material. Then, the leaf spring structure portion 56 is flexibly retracted with appropriate elasticity.

The protruding shaft 5 of the shaft member 5 is inserted into the shaft hole 62 of the bearing member 6.
2, the tip of the locking arm 53 is connected to any one of the click locking recesses 67 of the click locking mechanism 64 of the bearing member 6.
(Or 68), and is stably held at the engaged position by the elasticity of the leaf spring structure 56. By the action of this click locking mechanism 64, the swing range of the blind-like swing blade 4 is limited, and the posture is maintained in the open state shown in FIG. 1A or the closed state shown in FIG. 2B. Is done.

Reference numeral 7 denotes a surface of the outer wing portion 12 of the blind-like oscillating wing 4 which faces the inner wall portion 11 of the upper frame 1;
And a buffer sponge fixed to a surface of the inner wing portion 13 facing the outer wall portion 22 of the lower frame 2. When the blind-like swinging blade 4 is in a closed state, the buffer sponge 7 abuts. Alternatively, the airtightness at the time of closing the waterproof shutter can be improved by being in the interposed state.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the description of the above embodiment, two click locking recesses 5 are provided in a leaf spring structure 66 of a click locking mechanism 64.
7, 58 are constituted so that the sliding surfaces are continuous, and the shaft member 5 is formed.
The locking arm 53 is click-locked at two positions to hold the blind-like swinging wing 4 in the "open" or "closed" state. However, as shown in FIG.
By forming another locking recess 59 between 7, 58, the blind-like swinging blade 4 can be held in a half-open state.

[0016]

As described above, the waterproof shutter according to the present invention has a structure in which the blind-like swinging wings provided between the rectangular frames looks like two blinds by bending a single metal plate. This has the feature that the structure is simplified and the size can be reduced.

Also, a click locking mechanism is provided which elastically selectively engages the locking arm integrating the blind-like swinging blade with the protruding shaft with the plurality of click locking recesses integrated with the shaft hole. The blind-like oscillating blade can be securely held at the open position, the closed position, or the half-open position, and the like, and the effect of the present invention is extremely large.
