Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to insect-proof and anti-mold shutters, and in particular, relates to a shutter that is installed in a building opening or the like and can prevent intrusion of moths, insects, etc. into the building by performing reliable shielding.
[Prior art]
The shutter structure is used in various places such as manufacturing plants, warehouses, stores, garages, etc., and the materials of the shielding members used in them are various, such as those made of metal such as steel and aluminum, Or the resin-made sheet-like thing which gave resin coating to polyester is mentioned.
[0003]
Conventionally, in the vertical opening / closing type shutter, as shown in FIG. 18, the upper end of the shielding member 4a is directly connected to the drum 3a for lifting and feeding, and the shielding member 4a is wound around this drum. It was. With such a winding method, physical connection between the shielding member 4a and the drum 3a and the storage case 2a cannot be performed, and it is impossible to completely shield the gap. Due to this gap, not only the inside of the storage case communicates with the outside world, but as a result, the inside of the building is constantly exposed to the outside, and this gap allows moths and insects to enter the building. The intrusion route A was formed and caused various damages.
[0004]
Several ideas have been made so far to eliminate such a gap, but basically all are based on the same idea, and the shielding of the upper gap of the vertical open / close shutter was not perfect. The idea is to minimize the clearance by bringing a resilient material such as rubber or vinyl resin into close contact with the shielding member (see, for example, Patent Documents 1 and 2). As long as the shielding drum pulling drum is a moving part, the existing winding method could not create a sealed structure. In addition, since these shielding auxiliary parts are always in close contact with the shielding member, the function is significantly deteriorated by being worn at the time of opening and closing or being bitten by wrinkles or the like.

In the embodiment of FIG. 1, the storage case 2 is installed horizontally on a pair of support frames 5 erected on both sides of the shielded part a , and a window hole 6 is opened at the front lower corner portion. Further, a drum 3 is installed in the storage case 2 with a part facing the window hole 6, and a storage part b is formed through a partition plate 7 standing in the back.
[0020]
The shielding member 4 fixes the upper end edge to the inner surface of the storage case 2 at the back of the drum 3 and hangs downward along the outer peripheral surface of the drum 3 to shield the shielded part a. Both sides of the shielding member 4 in the storage case 2 are slidably in contact with the inner surfaces of both side plates of the storage case. Further, the front surfaces on both sides of the shielding member 4 coming out of the storage case 2 are closed in contact with the rear surfaces of the support frames 5. Therefore, the front and rear of the shielding member 4 are reliably blocked. It should be noted that, for example, a hook-type locking frame having elasticity is provided on the back surfaces of both support frames 5 so as to sandwich both sides of the shielding member 4 so that the support frames 5 are brought into closer contact with each other. You can also It is also possible to provide the weight 8 described above at the lower end.
[0021]
Further, the drum 3 is rotated so that the shielding member 4 is pulled up by the frictional force at the contact portion between the drum 3 and the shielding member 4, and the raised shielding member 4 is stored in the storage portion b at the back of the drum 3. doing. Accordingly, in order to obtain the above frictional force, for example, it is preferable that the frictional resistance of the drum side surface of the shielding member 4 and the outer peripheral surface of the drum 3 is made large, or unevenness such as meshing of gears is provided.
[0022]
When the drum 1 is rotated from the state shown in FIG. 1, the shutter 1 lifts the shielding member 4 as shown in FIG. 3, and the raised shielding member 4 is naturally folded into the storage portion b and stored. The Next, when the shielding member 4 is further lifted, the shielded part a opens as shown in FIG. During closing, for example, the drum 3 the shielding member 4 is fed by the reverse rotation relative to the time of opening, descends weighting or weights added weight 8 if it is attached to the shielding member 4.
[0023]
FIG. 5 shows another embodiment. In the embodiment of FIG. 1, a large number of bent portions 9 crossing the shielding member 4 are provided at predetermined intervals, while the drum 3 is formed in the shape of a horizontal polygonal column. The one side viewed from the side is configured to correspond to the distance between the bent portions 9. And it accommodates in the accommodating part b in the zigzag folded state bent by each said bending part 9. As shown in FIG. The bent portion 9 may be of any form configured to be easily bent from that portion, for example, may have a hinge structure, or the portion may be formed in a concave groove or the portion formed thin. Alternatively, a composite form thereof can be adopted.
[0024]
FIG. 6 shows still another embodiment. In the embodiment of FIG. 5, a large number of pairs of protrusions 10 project from both sides of each bent portion 9, and a pair of rails 11 are formed at the back of the drum 3. It is extended. Each rail 11 extends from the upper end position on both sides of the drum 3 to the back. Then, the shielding member is pulled upward by the rotation of the drum 3, and each protrusion 10 is folded and stored in a zigzag manner at each bending portion 9 while being placed on each rail 11, and the shielded portion a is opened. At the time of closing, the shielding member 4 is fed out by rotating the drum reversely with respect to the opening time, and descends with the weight of the shielding member 4 or the weight including the weight 8 if attached.
[0025]
FIG. 8 shows still another embodiment. In the embodiment of FIG. 6, the drum 3 is formed in a horizontal cylindrical shape, and the shielding member 4 is formed of a material that is more easily deformed.
[0026]
FIG. 9 shows still another embodiment. In this embodiment, the storage case 2 does not require the storage portion b in the embodiment of FIG. Further, since the shielding member 4 is not slid and raised on the drum 3, the upper end connection portion can be connected to the lower end of the front surface of the storage case 2. However, the present invention is not limited to this, and the upper edge can be connected to the inner surface of the storage case. Further, in this embodiment, a pulling member 12 having one end fixed to the shielding member 4 and the other end connected to the drum 3 is provided.
[0027]
In the present embodiment, the traction member 12 has a sheet shape, but is not limited thereto, and may be a belt-like shape as shown in FIG. 12 or a string-like shape as shown in FIG. Alternatively, although not shown, a composite of these may be used. The fixing position of the pulling member 12 to the shielding member 4 can be appropriately selected in consideration of requirements such as the size of the storage case 2 and the size of the shielding member 4. arbitrary preferred that it from providing traction starting member downward.
[0028]
In this case, the molding material can be selected for the shielding member 4 and the pulling member 12 in the same manner as in the invention of FIG. 1 described above. Made of resin, the lower half of the traction member 12 and the shielding member 4 is made of metal, the upper half of the shielding member is made of synthetic resin, the shielding member 4 is made of metal, and the traction member is made of metal wire. It is.
[0029]
The pulling member 12 and the shielding member 4 are sequentially wound around the drum 3 and stored in the storage case 2. For example, when the drum 3 is rotated from the state shown in FIG. 9, the pulling member 12 is first wound around the drum 3 as shown in FIG. 10, and the shielding member 4 is also lifted upward from the fixed position in conjunction therewith. Next, the rotation of the drum 3 is continued. As shown in FIG. 11, the shielded part a is opened by winding the shielding member 4 next to the pulling member 12. Further, when the drum is closed, the shielding member 4 is fed out by rotating the drum reversely with respect to the opening time, and descends with the weight of the shielding member 4 or the weight including the weight 8 if attached.
[0030]
FIG. 14 shows still another embodiment. In this embodiment, in the embodiment of FIG. 9, guide grooves 13 are vertically provided in the respective support frames 5. Further, the shielding member 4 is provided with a large number of crossed bent portions 9 at predetermined intervals, and a large number of protrusions 10 protruding from both sides of each bent portion 9 are fitted in the guide grooves 13 so as to be vertically movable. The shielded part a is shielded together. In this case, the shape of the bent portion 9 may be the same as that described in the embodiment of FIG.
[0031]
Furthermore, the pulling member 12 in this embodiment is configured by fixing one end to the lower end portion of the shielding member 4 and connecting the other end to the drum 3. In this case, the shielding member 4 and the pulling member 12 can employ the same material and form as described above.
[0032]
Then, as the pulling member 12 is wound around the drum 3, the shielding member 4 is folded and raised by bending at each bending portion 9. That is, the pulling member 12 is pulled upward by the rotation of the drum 3 from the state shown in FIG. 14, and the lower end of the shielding member 4 is raised as shown in FIG. At this time, since each projection 10 of the shielding member 4 is fitted in the guide groove 13, it moves only in the vertical direction, and the bent portion 9 is bent outward by a force from below. Further, the rotation of the drum 3 is continued, and as shown in FIG. 17, when the shielding member 4 is folded, the shielded portion a is opened. Although the bending direction of the shielding member 4 in the illustrated example is the outside of the building, this bending direction depends on the shape of the support frame, the direction of bending of the bent portion, etc. Can be created.
[0033]
【The invention's effect】
As described above, the shutter according to the present invention includes the storage case 2 installed on the shielded part a, the drum 3 for lifting and feeding installed in the case, and the inner surface of the storage case 2 at the back of the drum 3. And a sheet-like shielding member 4 that hangs downward along the outer peripheral surface of the drum 3 and shields the shielded part a. The drum 3 is rotated to rotate the drum 3. Since the shielding member 4 is pulled up by the frictional force at the contact portion with the shielding member 4 and the raised shielding member 4 is housed in the housing part b at the back of the drum 3, It is possible to dramatically reduce various damage caused by them inside the building by completely breaking off the path of insects and insects. Moreover, since various materials can be applied to the shielding member, it is possible to complete a product having various basic performances such as crime prevention, high-speed opening and closing, and insect-proofing / anti-molding effects.
[0034]
Further, the shielding member 4 is a shielding member provided with a large number of transverse bent portions 9 with a predetermined interval, and the storage in the storage portion b is in a zigzag folded state bent at each of the bent portions 9. In this case, the shielding member 4 can be housed in the housing portion b in an orderly manner and can be smoothly inserted and removed.
[0035]
Further, when the drum 3 has a horizontal polygonal column shape and one side viewed from the side is a drum corresponding to the distance between the bent portions 9, the shield member 4 is lifted and fed out more reliably and slid. It can be performed without any problems and smoother shielding members can be taken in and out.
[0036]
A pair of rails that are provided with a plurality of bent portions 9 across the predetermined interval and provided with a shielding member 4 projecting a plurality of pairs of protrusions 10 on both sides of the bent portion 9 and extending to the back of the drum 3. 11 is configured such that each projection 10 is placed on 11 and stored in the storage portion b in a zigzag folded state bent at each bending portion 9. It has the advantage that it can be stored in an orderly manner and can be taken in and out more smoothly.
[0037]
The traction member 12 has one end fixed to the shielding member 4 and the other end connected to the drum 3. The traction member 12 and the shielding member 4 are sequentially wound around the drum 3 and stored in the storage case 2. In this case, the shielding member 4 can be lifted directly by lifting the drum rather than the frictional force with the drum, so that the shielding member 4 can be lifted more reliably, and the shielding member 4 can be suspended from the front surface of the storage case. Since it can be provided, it has advantages such as easier sealing of both sides of the shielding member .
[0038]
Further, a large number of bent portions 9 that cross the shielding member 4 are provided at predetermined intervals, and a large number of pairs of protrusions 10 are provided on both sides of each bent portion 9, and each protrusion is guided to each guide of the support frame 5. To fit the groove 13 so as to move up and down, and to fix one end to the lower end portion of the shielding member 4 and to connect the other end to the drum 3, the winding member 12 is wound around the drum 3. Accordingly, in the structure in which the shielding member 4 is folded and raised at each bending portion 9, similarly, the shielding member 4 can be lifted directly by the drum rather than the frictional force with the drum. Since the shielding member can be lifted up and the shielding member 4 can be suspended from the front surface of the storage case, it has advantages such as easier sealing of both sides of the shielding member .
