Prior to the description of the invention, for convenience of explanation, if a non-strict directional reference system is specified with reference to the attached surface, up and down (y), left and right (x), front and rear (z) in the state as shown in FIG. 2 In the description related to the other drawings, the direction is specified according to this criterion.

The thermal insulation shutter according to the present invention may be largely defined as including a winding roll 1 and a plurality of unit slats 2 as shown in FIG. 1.

A plurality of unit slats (2) are configured to be wound on the winding roll (1) in a state in which they are installed adjacent to each other in the vertical direction, so that the unit slats (2) are attached to the winding roll (1) according to the operation of the winding roll (1). Opening and closing of the doorway in which the insulation shutter is installed can be made while being removed or released.

Although not shown, the winding roll 1 may be driven to rotate in the forward and reverse directions by the driving force of a separate driving motor, and the user may directly control the driving motor to open/close the door on which the shutter is mounted.

The unit slats 2 may be formed to extend long in the left and right directions, and the length may be variously modified in consideration of the specifications of the entrance to which the insulating shutter is to be mounted.

Each of the plurality of unit slats (2) has an upper hook (11) and a lower hook (12) formed at the upper and lower ends, and the inner space (14) is divided into two parts by the guide plate (13). The body portion 10, the cover portion 20 arranged to be spaced apart at a predetermined interval on the front of the body portion 10, the body portion 10 and the body portion 10 is mounted between the upper and lower portions of the cover portion 20, respectively. ) And the cover part 20 may be defined as including a pair of insulating materials 30 forming a filling space between the filling space and a filling material 40 filled in the filling space.

The body portion 10 is a member facing the interior, based on a state in which the unit slat 2 is closed, and may be formed in a profile shape in which the top, bottom, front, and rear surfaces are closed.

An upper hook 11 is formed on the upper surface of the body 10, and a lower hook 12 is formed on the lower surface of the body 10, and a front plate 10a is formed at the front, and a rear plate 10b is at the rear. ) Are arranged in parallel to connect the upper hook (11) and the lower hook (12) to form an inner space (14) between the front plate (10a) and the rear plate (10b) to form the body part (10) The front plate 10a divides the filling space and the inner space 14 back and forth, so that the insulation material 30a, 30b and the filler 40 are located in the front based on the front plate 10a of the body 10. The inner space 14 may be configured separately from each other. The upper hook (11) and the lower hook (12) may be formed in a hook shape, and the upper hook (11) includes a lower hook (12) of the adjacent unit slat (2), and the lower hook (12) The upper hooks 11 of the adjacent unit slats 2 may be entangled so that they may be bound together.

The unit slats 2 adjacent to the upper hook 11 and the lower hook 12 may be rotated with each other.

The rear surface of the body portion 10 is formed to be curved in an arc shape, and is configured to have a complementary relationship with the shape of the cover portion 20 to be described later.

This induces the cover part 20 of the unit slat 2 adjacent to the body part 10 of the unit slat 2 to contact more closely when the unit slat 2 is wound on the winding roll 1, This is to minimize the volume of the rolled insulation shutter.

The upper first fastener 15 and the lower first fastener 16 in which a first fitting groove 17 to which the rear end of the heat insulating material 30 is fitted are recessed are formed at the front upper and lower ends of the body part 10. It can be formed to protrude.

The cover part 20 is a member facing the outdoor side based on the state in which the unit slat 2 is closed, and is formed to extend in the left and right directions to correspond to the length of the body part 10, and extends the front side. It can be formed to be curved in a convex arc shape. In addition, the induction line 21 may be recessed along the left and right longitudinal directions of the cover part 20 on the front surface of the cover part 20. Through this, it is possible to disperse the external wind pressure that strikes the front of the cover part 20, so that effects such as noise reduction can be expected.

An upper second fastener 22 and a lower second fastener 23 protrude from the rear surface of the cover 20 to face the upper first fastener 15 and the lower first fastener 16, respectively. In addition, a second fitting groove 24 to which the front end of the heat insulating material 30 is fitted may be recessed in the second fasteners 22 and 23.

The insulating material 30 is interposed between the first fasteners 15 and 16 and the second fasteners 22 and 23 facing each other to mechanically connect the body portion 10 and the cover portion 20. The heat insulating material 30 may be formed to extend in left and right directions along the length direction of the body portion 10 and the cover portion 20.

The insulation material 30 may be composed of an upper insulation material 30a mounted on the upper portion of the body portion 10 and the cover portion 20, and a lower insulation material 30b mounted on the lower portion. The filling space between the body portion 10 and the cover portion 20 may be sealed.

The heat insulating material 30 has the purpose of preventing cold air or heat from being conducted indoors, and may preferably be made of cured polyamide.

Polyamide has excellent physical properties such as abrasion resistance, chemical resistance, and thermal insulation, and thus provides structural strength of the unit slat 2 and can guarantee the thermal insulation performance of the unit slat 2 itself.

A protruding piece 31 fitted into the first and second fitting grooves 17 and 24 may protrude from the heat insulating material 30. In particular, the upper insulator (30a) has an upper protruding piece (32) is formed to protrude to the upper surface height of the upper first fastener 15 and the upper second fastener (16) to the upper center of the body portion (10) It may be formed to be exposed to the outside between the and the cover portion 20.

The lower surface of the upper insulating material 30a is exposed to the filling space, and the upper surface is configured to be exposed to the outside between the body portion 10 and the cover portion 20.

This is to improve the cushioning effect and airtightness by enabling the upper insulating material 30a to make elastic contact with the first gasket 50 to be described later.

The filler 40 is composed of polyurethane foam that is filled into the filling space, and, like the insulation 30, performs an insulation function.

It is revealed that the above-described insulating material 30 and filler 40 can be modified with various known materials other than polyamide and polyurethane foam.

On the other hand, the unit slats 2 are mounted on the rear surface of the first gasket 50 and the body 10 mounted under the lower insulating material 30b among the pair of insulating materials 30, and thus a plurality of unit slats 2 It may further include a second gasket 60 configured to come into contact with the front surface of the cover portion 20 of the adjacent unit slat 2 when wound by the winding roll 1.

The first gasket 50 and the second gasket 60 are members extending left and right along the longitudinal direction of the unit slat 2 and may be made of an elastic material such as rubber or silicone.

In a state in which the unit slats 2 are closed, for example, in a state in which a plurality of unit slats 2 are connected in the up and down directions, there is a concern that draft and rain may flow into the adjacent unit slats 2, at this time, The first gasket 50 serves to close a point between adjacent unit slats 2.

To mount the first gasket 50, a first fitting protrusion 18 is formed protruding from the lower first fastener 16 on the body portion 10, and the first fitting protrusion 18 is formed on the rear surface of the cover portion 20. The second fitting protrusion 25 may protrude to face the first fitting protrusion 18. When configured in this way, a slit space is provided between the lower first fastener 16 and the first fitting protrusion 18, and between the lower second fastener 23 and the second fitting protrusion 25, and the slit space The first gasket 50 is configured to protrude downward in a state in which it is inserted, and is configured to be in elastic contact with the upper surface of the upper protruding piece 32 of the upper insulating material 30a of the unit slat 2 adjacent to the lower part.

In the process of operating the shutter, a damping effect can be expected due to the elastic contact between the first gasket 50 and the insulating material 30, reducing noise as well as sealing the points between adjacent unit slats 2 more airtightly. Or rainwater can be prevented from entering.

The second gasket 60 may protrude to the rear of the body portion 10 while being inserted into the rear groove 61 formed on the rear surface of the body portion 10. The second gasket 60 elastically contacts the cover part 20 of the unit slat 2 adjacent to the rear when the unit slat 2 is wound around the winding roll 1 as shown in FIG. 7 to make contact noise. It plays a role in reducing the value.

If the second gasket 60 is configured as described above, noise generated by colliding with each other during the opening and closing operation of the shutter can be significantly reduced.

The first gasket 50 and the second gasket 60 may be used differently only at locations to be installed using the same member.

On the other hand, at the front center of the body portion 10, a circular guide piece 19 in which a part of the circumference is cut in the direction facing the body portion 10 is formed, and the guide plate 13 is a guide piece 19 It has a configuration that divides the inner space 14 in the upper and lower directions by connecting the rear surface of the body part 10 and the body part 10.

By the interaction of the guide plate 13 and the guide piece 19, the inner space 14 of the body portion 10 may be formed in each of the upper and lower directions.

At this time, the inner space 14 is configured as a vacant room, so that the thermal conductivity of the unit slat 2 itself is significantly lowered, thereby providing more improved thermal insulation performance.

More specifically, the filler 40 filled in the filling space may flow into the inside of the guide piece 19, and the filler 40 cured by flowing into the inside of the guide piece 19 is the guide piece 19 The mechanical bonding strength with and is improved so that the filler 40 can be firmly fixed inside the filling space.

The unit slat 2 may further include a finishing cover 3 and a guide roller 4 respectively mounted on the left and right ends of the unit slat 2.

At this time, the guide piece 19 is also used as a fitting groove for fitting of the finishing cover 3 or the guide roller 4 configured at the left and right ends of the unit slat 2 as shown in FIG. I can.

The finishing cover 3 may be mounted on the left and right ends of the unit slat 2 to prevent external exposure of the filling material 40, and at this time, the finishing protrusion 3 ′ of the sword cover 3 It may have a configuration that is fitted into the inside of the guide piece (19).

The guide roller 4 is a member for rolling contact with the guide structure (not shown) that guides the unit slat 2 in the process of taking up or unwinding the unit slat 2, and the left and right ends of the unit slat 2 It plays a role of reducing the frictional resistance between the unit slat (2) and the guide structure by supporting each rotation. At this time, the guide roller 4 may be formed with a fixed shaft (4'), the fixed shaft (4') has a configuration that is fitted into the guide piece (19).

In addition, it is possible to guide the hot or cold air conducted to the filler 40 to the guide plate 13 through a pair of front tips 19a formed by cutting a part of the circumference of the guide piece 19.

Since the guide piece 19 and the guide plate 13 are formed relatively thin, a structure in which hot or cold air conducted into the unit slat 2 can be induced more intensively is provided.

For example, in the case of the summer season, when the heat induced through the guide piece 19 (shown by the two-dot chain line) is conducted to the guide plate 13, as shown in FIG. The air filled in the inner space 14 formed in the lower part air-cools the guide plate 13 to lower the temperature of the guide plate 13.

That is, even if the heat conducted to the guide plate 13 is radiated from the guide plate 13, the air contained in the inner space 14 quickly cools the heat guided to the guide plate 13, and as a result, the outdoor heat is transferred to the indoor side. It is equipped with a structure that can prevent it from falling.

In addition, since the filling material 40 and the heat insulating material 30 biased to the outdoor side first block heat, and subsequently, secondary heat is blocked by the air filled in the inner space 14, the unit slat The heat shielding performance of (2) can be improved.

Even in the winter season, similar to the above, when the cold air induced through the guide piece 19 is conducted to the guide plate 13, the inner space 14 formed in the upper and lower portions based on the guide plate 13 There is a structure capable of preventing heat exchange from being carried out to the indoor side by heat exchange while the air filled in the cooled guide plate 13 increases the temperature. When such a cold air blocking structure is realized, it is possible to prevent condensation of water vapor on the rear surface of the body 10 due to a temperature difference between the outdoor side and the indoor side.

In addition, since the filling material 40 and the heat insulating material 30 biased to the outdoor side first block cold air, and then, secondary to the air filled in the inner space 14, it has a structure to block cold air, so the unit slat The cold air blocking performance of (2) can be improved.

An auxiliary guide piece 19 ′ may be additionally formed on the front side of the body part 10 with the guide piece 19 in the center. The auxiliary guide piece 19 ′ has a structure and function similar to that of the guide piece 19 described above, and through this, it is possible to expect effects such as increase in mechanical bonding force with the additional filler 40 and increase in insulation performance.

On the other hand, there is a concern that members such as the cover part 20, the filler 40, and the heat insulating material 30 located on the outside side relatively thermally expand due to the increase in temperature on the outdoor side during the summer season, causing a torsion to be applied to the unit slat 2. At this time, since the guide piece 19 and the auxiliary guide piece 19' are strongly coupled to the filler 40, the shape stability of the unit slat 2 can be ensured.

Hereinafter, a schematic assembly process of the unit slat 2 will be described.

First, the body portion 10, the cover portion 20, the heat insulating material (30a, 30b), the first gasket 50, the second gasket 60, and the finishing cover (3) is prepared.

The upper first fastener 15 and the lower first fastener 16 formed on the front of the prepared body 10, the rear protruding pieces 31 of the upper insulation 30a and the lower insulation 30b are respectively fitted and combined. Let it. Then, after arranging the cover part 20 to face the front of the body part 10, the front end protrusions 31 of the upper and lower insulating materials 30a and 30b are formed on the rear surface of the cover part 20. The body part 10, the cover part 20, and the heat insulating material 30 are assembled by being fitted into the upper second fastener 22 and the lower second fastener 23, respectively.

In this configuration, a filling space may be formed between the body portion 10, the cover portion 20, and the heat insulating material 30, and the filling material 40 is injected into the filling space formed in this way.

When the filling material 40 is injected, the closing cover 3 is installed at the left and right ends of the open unit slat 2, and the first gasket 50 is first fitted with the lower first fastener 16 Between the jaws 18, the lower second fastener 23 and the second fitting jaw 25 is fitted in the slit space.

Subsequently, the second gasket 60 is inserted into the rear groove 61 formed on the rear surface of the body 10 to complete the assembly of the unit slat 2.
