Description

SHUTTER HAVING GOOD INSULATION AND SOUND ISOLATION

The present invention relates to a shutter, and to a shutter having excellent insulation and sound insulation effects that can enhance insulation and sound insulation effects without left and right flow.

In general, shutters for buildings have a security function that prevents outsiders from entering the interior, a fire protection function that prevents fire from falling when a fire occurs in a specific space, an airtight function that blocks outside air, and internal heat energy. It has a thermal insulation function to prevent the transfer to the outside.

Building shutters are a combination of slats with narrow and long lengths. The slats are combined with the engaging hook and the locking jaw provided in the upper and lower continuously to form a large area shutter. Shutters are provided on both sides of the guide rail to help the movement of the slats, and provided on the ceiling of the building includes a shutter box for winding up and down the slats.

An example of such a conventional shutter has been disclosed in Korean Utility Model Registration No. 20-0429772, "Shutter having a C-type guide."

By the way, the conventional slat 10 has a free space formed between the locking groove and the locking hole to be folded by the rotation of the shutter box (2). When a strong wind blows or an external force is applied by such a clearance, the slat 10 may be moved left or right.

Thus, when the slat 10 is moved left and right there is a problem that the slat 10 located in the vertical direction can move in the opposite direction or the slat 10 can be separated from the guide rail (not shown). In order to solve this problem, both ends of the slat 10 are coupled to the cap 60 to prevent the separation of the slats from the guide rail. Accordingly, there is a disadvantage in that the assembly structure of the entire shutter 1 is complicated and the manufacturing cost is increased.

On the other hand, the outside air is introduced through the free space formed in the coupling area of the slat 10 arranged up and down adjacent to the inner space airtightness is very low, there is a problem that the heat insulation effect is reduced, there is a problem that can not block the surrounding noise. .

An object of the present invention is to solve the above problems, while inserting the insulating material between the upper and lower neighboring double slats while preventing the flow of the slats, to increase the insulation effect by shielding the free space can improve the airtight and sound insulation effect It is to provide a shutter with excellent insulation and sound insulation.

Another object of the present invention is to provide a shutter having excellent thermal insulation and sound insulation, which provides airtightness and thermal insulation without interfering with the movement of the folded or unfolded slats.

The above objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention by those skilled in the art.

The object of the present invention can be achieved by a shutter. The shutter of the present invention comprises: a plurality of slats arranged continuously up and down; It includes an elastic packing coupled in the longitudinal direction to the coupling region of the pair of slats disposed adjacent to the top and bottom, the plurality of slats are each provided with a slab body in which a heat insulating material is accommodated therein and having a predetermined area Wow; A catch ring formed at an upper portion of the slat body; And a locking jaw bent in the opposite direction to the locking ring at the bottom of the slat body, wherein the elastic packing is disposed up and down next to each other and is disposed in a longitudinal direction between the locking jaw of the upper slat and the locking ring of the lower slat. It is characterized by being coupled along.

In the shutter 100 according to the present invention, the elastic packing 140, 140a is coupled between a pair of slats 110, 120, and 130 disposed up and down adjacent to prevent left and right movement of the slats 110, 120, and 130, and between the slats 110, 120, and 130. It prevents the inflow of outside air through the bonding area of and improves the insulation and sound insulation effect by maintaining airtightness.

As shown in FIG. 2, the shutter 100 is formed by combining a plurality of slats 110, 120, and 130 up and down. The plurality of slats (110, 120, 130) are arranged perpendicular to the ground in the unfolded state to block the space, as shown in Figure 5 when the winding means 160 is operated a plurality of slats (110, 120, 130) are folded together It is wound around 160 to open the space.

Here, for the convenience of description, a state in which three slats 110, 120, and 130 of the upper slat 110, the middle slat 120, and the lower slat 130 are combined will be described as an example.

 Since the upper slat 110, the middle slat 120 and the lower slat 130 has the same structure, only the upper slat 110 will be described in detail. The upper slat 110 has an upper slat body 111 formed in a bar shape having a long left and right sides, an upper hook ring 113 formed by bending at an upper portion of the upper slat body 111, and an upper slat body 111. The upper locking jaw 115 is formed at the bottom of the upper hook ring 113 is bent in the opposite direction.

The upper slat body 111 is the front plate 111a, the back plate 111b formed to be spaced apart from the front plate 111a by a predetermined interval, and the heat insulating material accommodated between the front plate 111a and the back plate 111b ( 111c). The front plate 111a and the back plate 111b are formed of a metal material. Since the plurality of slats 110, 120 and 130 are repeatedly moved up and down along the guide rails 150 and 150a, the front plate 111a and the back plate 111b are formed of a metal material having durability.

The heat insulating material 111c is accommodated in the front plate 111a and the back plate 111b to prevent heat from flowing out to the outside to improve heat insulating performance.

The upper catching ring 113 is integrally formed on the upper portion of the upper slat body 111. The upper catching ring 113 is formed by bending the front plate 111a and the back plate 111b after extending in the upper direction.

The upper locking jaw 115 is formed integrally extended to the lower portion of the upper slat body 111. The upper locking jaw 115 is formed by bending the front plate 111a and the back plate 111b after being extended in the downward direction. At this time, the upper catching jaw 115 is bent in a direction opposite to the upper catching ring 113.

For example, as shown in FIG. 2, the upper catching ring 113 is bent upward toward the front plate 111a, while the upper catching jaw 115 is bent downward toward the rear plate 111b. Is formed.

The upper catching ring 113 and the upper catching jaw 115 act as a means by which the slats 110, 120, and 130 located above and below can be unfolded or folded.

 Each of the locking jaws 115, 125, and 135 provides a space in which each of the locking rings 113, 123, 133 can be rotatably accommodated, and the locking rings 113, 123, 133 are engaged with the locking jaws 115, 125, 135. That is, the middle engaging ring 123 of the intermediate slat 120 is engaged with the upper engaging jaw 115 of the upper slat 110, and the lower slat 130 with the intermediate engaging jaw 125 of the intermediate slat 120. The lower hook 133 is engaged.

At this time, in order to ensure the ease of coupling between the slats (110, 120, 130) and the turning radius to facilitate the folding and unfolding of the slats (110, 120, 130), each hook ring (113, 123, 133) is a predetermined interval from the top of each slat body (111, 121, 131) It is formed leaving a free space (117).

 As a result, the hooks 113, 123, and 133 are rotated in the state accommodated in the hooks 115, 125, and 135, and the neighboring slats 110, 120, and 130 may be folded or unfolded.

In addition, the circumferential lengths of the hooks 113, 123, and 133 are formed to have a predetermined length shorter than the circumferential lengths of the catching jaws 115, 125, and 135. That is, as shown in Figure 4, the length of the ring ends 113a, 123a of the hooks 113, 123, 133 is formed shorter than the tip of the jaw (115a) of the locking jaw (115, 125, 135) surrounding the outer ring ends (113a, 123a) ) Is supported in contact with the inner surface of the jaw end 115a of the locking jaw (115, 125, 135) and the position is fixed. As a result, the engagement states of the hooks 113, 123 and 133 and the hooking jaws 115, 125 and 135 are maintained so that the assembled state of the plurality of slats 110, 120 and 130 is stably maintained.

Meanwhile, even when the adjacent slats 110, 120, and 130 are folded as shown in FIG. 5, the hooks 113, 123, 133 and the latching jaws 115, 125, and 135 are contacted with the inner curved surface in different directions and are separated from the outside. Is prevented.

Due to the shape of the hooks 113, 123, 133 and the hooking jaws 115, 125, and 135, the assembly of the slats 110, 120, and 130 adjacent to each other in the vertical direction is fitted in a sliding manner from the side.

Elastic packing (140,140a) is coupled to the coupling region of the neighboring slats (110,120,130) to prevent the movement of the slats (110,120,130) and block the inflow of outside air. The elastic packings 140 and 140a are formed of a rubber or silicone material having elasticity so that neighboring slats 110, 120, and 130 do not interfere with each other when they are folded or unfolded.

The elastic packings 140 and 140a are disposed in the coupling region of the catches 113, 123, 133 and the catching jaws 115, 125, and 135 of the slats 110, 120, and 130 disposed up and down.

For convenience of description, the first elastic packing 140 coupled between the upper slat 110 and the middle slat 120, and the second elastic packing 140a coupled between the middle slat 120 and the lower slat 130. The explanation is divided into). The first elastic packing 140 and the second elastic packing 140a have the same configuration only in positions.

As described above, the hooks 113, 123, 133 are formed with a free space 117 from the upper surface of the slat body (111, 121, 131) for smooth rotation of the hooks (115, 125, 135). The elastic packing 140 and 140a may be formed by applying a liquid elastic resin A to the free space 117 and curing the free space 117 as shown in FIG. 3.

In the state where the upper slat 110 and the intermediate slat 120 are coupled to each other, the worker arranges the elastic resin injection means 200 in the free space 117, and then presses the elastic resin injection means 200 to the elastic resin (A) is sufficiently injected into the free space 117. In this manner, the elastic resin injection means 200 is moved along the longitudinal direction of the free space between the upper slat 110 and the intermediate slat 120 to inject the elastic resin A.

The injected elastic resin (A) is cured between the upper locking jaw 115 and the intermediate locking ring 123 and forms the first elastic packing 140. In the same manner, a second elastic packing 140a is formed by injecting an elastic resin A between the intermediate locking jaw 125 and the lower locking ring 133.

 The first elastic packing 140 formed as described above fills the free space 117 to the thickness of the free space 117 as shown in FIG. 4. While the first elastic packing 140 blocks the free space 117, the upper portion of the first elastic packing 140 is fixed to the upper locking jaw 115 of the upper slat 110, and the lower portion of the intermediate slat 120 is closed. It is fixed to the intermediate hook 123. Since the positions of the upper slats 110 and the middle slats 120 are fixed through the first elastic packing 140, the upper slats 110 and the middle slats 120 flow left and right even when external force is applied or a strong wind blows. Is prevented.

In addition, since the first elastic packing 140 blocks the free space 117, the external air is blocked from moving between the slats 110, 120, and 130 adjacent to the upper and lower sides, thereby increasing the insulation effect.

The first elastic packing 140 is formed by injecting an elastic resin (A) in a state in which the upper slat 110 and the middle slat 120 are vertically unfolded. Accordingly, as shown in FIG. 4, the initial shape of the first elastic packing 140 corresponds to the gap of the free space 117.

As shown in FIG. 5, the plurality of slats 110, 120, 130 are moved upward along the guide rails 150, 150a by the winding means 160, and the slats 110, 120, 130 are wound around the outer periphery of the winding means 160. When the neighboring slats (110, 120, 130) are folded to each other.

5, when the upper slat 110 and the middle slat 120 are folded, the first elastic packing 140 positioned therebetween is elastically compressed. When the winding means 160 releases the winding force, the plurality of slats 110, 120, and 130 are vertically unfolded. At this time, the elastically compressed first elastic packing 140 acts an elastic force to restore to the initial shape, by the restoring force the upper slat 110 and the middle slat 120 is a conventional slat without elastic packing Can be deployed faster than

6 is an exemplary view showing a modification of the shutter 100a of the present invention. The shutter 100 of the above-described preferred embodiment first assembles the adjacent slats up and down, and then injects and hardens the liquid elastic resin to form an elastic packing.

On the other hand, the shutter 100a according to the modification is formed by forcibly injecting the elastic packing 140 ', 140a', which is already manufactured, into the free space 117 between the adjacent slats 110, 120, 130. Elastic packing 140 ', 140a' is formed of a rubber or silicone material.

At this time, the elastic packing 140 ', 140a' is formed to have a cross-section of the half moon or crescent moon corresponding to the shape of the free space. In addition, the engaging end 141 bent toward the inner side is formed at the insertion side end inserted into the elastic packing (140 ', 140a).

When forcibly pushed into the free space 117 from the locking end 141 side, it is elastically contracted and is restored to the initial state after being inserted into the free space 117. The inserted locking end 141 protrudes into the upper locking jaw 115 as shown in FIG. 6 and is engaged with the upper locking jaw 115. As a result, the positions of the elastic packings 140 'and 140a' are restrained between the free space 117 and the upper locking jaw 115.

The elastic packings 140 'and 140a' fitted into the free space 117 enhance the thermal insulation effect and fix the positions of the adjacent slats 110, 120 and 130.

As described above, the shutter according to the present invention has an elastic packing formed of an elastic material between adjacent slats. Elastic packing prevents the inflow of outside air without interfering with the operation of unfolding and folding the slats, thereby improving insulation and sound insulation by maintaining airtightness.

In addition, the elastic packing blocks the movement of the slats so that a separate cap is not necessary. Accordingly, the assembly process of the shutter door can be simplified, and the manufacturing cost can be reduced.

In addition, the slats folded by the elastic restoring force of the elastic packing can be unfolded more quickly, thereby reducing the total time taken to release the wound shutter.

The embodiment of the shutter of the present invention described above is merely exemplary, and those skilled in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. will be. Therefore, it will be understood that the present invention is not limited to the forms mentioned in the above detailed description.
