In addition, the inner side means the inside of each member such as the body portion 51 of the case 11 or the gasket 5 to be described later, and the outside means the outside of each member, so apply the same in the following description do it with

The case 11 may include a vertical plate 111 connected to a vertical fitting part 13 to be described later by way of example, and a horizontal plate 112 extending in the horizontal direction from the top or bottom of the vertical plate 111 . .

That is, in a state in which the vertical plate 111 is erected in the vertical direction, the horizontal plate 112 extends from the top or bottom of the vertical plate 111 in the horizontal direction.

In FIG. 3 , the horizontal plate 112 is illustrated as extending from the upper end of the vertical plate 111 .

In addition, the case 11 may include a pair of finishing plates 113 connected to the horizontal plate 112 and the vertical plate 111 . A pair of finishing plates 113 are arranged so that the inner surfaces face each other based on the longitudinal direction of the horizontal frame 2 connected to the horizontal fitting portion 12 to be described later, the vertical plate 111 and the horizontal plate 112 . and may be connected to form the installation space.

The horizontal fitting part 12 is installed in the case 11 and protrudes in the horizontal direction. Illustratively, the horizontal fitting portion 12 may be installed in the installation space of the case 11 and extend in the horizontal direction to form a protruding portion protruding from the case 11 when viewed from the front.

2, in the prior art (prior art 2), the ends forming the protrusion direction cross section of the protrusion P are connected, so that more material (for example, molten metal) is formed to form the protrusion P. Although the use was required, as shown in FIGS. 3 to 5 , this coupler has the advantage that less material can be used because the protruding direction cross-sections of the horizontal fitting part 12 and the vertical fitting part 13 are cut off.

In addition, referring to FIG. 2 , in the prior art (prior art 2), there is a risk that the end forming the protruding direction cross section of the protrusion P is connected, so that the glass may be damaged when the glass is inserted.

However, as shown in FIGS. 3 to 5 , in this coupler, the horizontal fitting portion 12 and the vertical fitting portion 13 are each cut off in the protruding direction cross section, and in particular, the outer vertical part 121 and the outer horizontal part 131 are It is connected to the finish plate 113, and the horizontal part 122 and the vertical part 132 are connected to the horizontal plate 112 and the vertical plate 111, respectively, so that the horizontal fitting part 12 and the vertical fitting part 13 are Since the arrangement in the inner installation space of the case 11 is minimized, the soundproof material 4 such as glass is effectively suppressed from being damaged by suppressing contact with the soundproof material 4 to be described later that is fitted in the inner installation space of the case 11 . There are advantages to being able to

In addition, in the prior art (Prior Art 2, see FIG. 2), the body (B) is composed of an outer plate and an inner plate, making it difficult to insert the lifting ring for lifting, and in this case, an accident (breakage, etc.) may occur during lifting. However, this coupler does not have a configuration corresponding to the inner plate on the inside of each of the vertical plate 111 and the horizontal plate 112 where the case 11 forms an installation space, so it is easy to install a device such as a lifting ring for lifting There is an advantage that

3 to 5 , this coupler may include a through hole 114 formed to penetrate the outer surface and inner surface of at least one of the vertical plate 111 and the horizontal plate 112 .

In this way, by including the through hole 114 in this coupling port, it is easy to install the lifting ring and the like, and the degree of insertion of the soundproofing material 4 to be described later in the installation space of the case 11 can be confirmed, and the through hole There is an advantage that the soundproofing material 4 or the frames to be described later can be pushed through the 114 so that the separation of the present coupling member and the soundproofing material 4 can be more easily performed.

3 to 5 , the horizontal plate 112 may include a vertical connecting protrusion 112a that protrudes in a vertical direction and is connected to the horizontal fitting part 12 .

Through this, when the horizontal frame 2 to be described later is coupled to the horizontal fitting part 12, the horizontal frame 2 is supported by the vertical connecting protrusion 112a to add structural stability (see FIG. 6 to be described later). ).

In addition, the vertical plate 111 may include a horizontal connection protrusion 111a that protrudes in the horizontal direction and is connected to the vertical fitting part 13 .

Through this, when the vertical frame 3 to be described later is coupled to the vertical fitting portion 12, the vertical frame 3 is supported by the horizontal connecting protrusion 111a to add structural stability (see FIG. 6 to be described later). Reference).

3 to 5, this coupler protrudes outward from the outer surface of the horizontal fitting part 12, the horizontal fitting protrusion 14 formed along the protruding direction (horizontal direction) of the horizontal fitting part 12. may include

In this case, the horizontal length of the horizontal fitting projection 14 may be shorter than the horizontal length of the horizontal fitting portion 12 (the portion protruding from the case 11 is shorter).

Through this, as shown in FIG. 6 to be described later, when the horizontal frame 2 moves toward the case 11 and the horizontal fitting part 12 is inserted into the insertion hole of the horizontal frame 2, the initial insertion is facilitated, and thereafter, the horizontal When the frame (2) moves further toward the case (11), the horizontal fitting portion (12) and the horizontal frame (2) are press-fitted by the horizontal fitting projection (14), and the horizontal fitting portion (12) and the horizontal frame (2) are The bonding strength can be improved.

Similarly, this coupler may include a vertical fitting protrusion 15 that protrudes outward from the outer surface of the vertical fitting 13 , and is formed along the protruding direction (vertical direction) of the vertical fitting 13 .

In this case, the vertical length of the vertical fitting protrusion 15 may be shorter than the vertical length of the vertical fitting portion 13 (the portion protruding from the case 11 is short).

Referring to FIG. 6 to be described later, the frames (horizontal frame 2 and vertical frame 3) to be described later may include insertion grooves 21 and 31 into which a soundproofing material 4 to be described later is inserted and installed. .

At this time, referring to FIGS. 3 to 5 , the height (vertical length) of the vertical plate 111 and the horizontal length of the horizontal plate 112 may be greater than the depth of the insertion grooves 21 and 31 of the frames.

Referring to FIG. 3, for example, if described in more detail, the horizontal length of the horizontal plate 112 is formed to be greater than the depth of the insertion groove 31 recessed inward from the outer surface of the vertical frame 3, Therefore, it is suppressed that the edge of the soundproofing material 4 fitted into the insertion groove 31 comes into contact with the vertical plate 111 extending in the vertical direction from the end of the horizontal plate 112 .

Therefore, it is possible to prevent the soundproofing material 4 to be described later fitted into the frames from contacting the vertical plate 111 and the horizontal plate 112, respectively, so that the soundproofing material 4 such as glass can be effectively suppressed from being damaged. There is this.

Referring to FIG. 3 , when the horizontal fitting part 12 and the vertical fitting part 13 of the frame coupler 1 according to the first embodiment of the present invention will be described in more detail, the horizontal fitting part 12 is horizontal It may include an inner vertical part 123 extending in a vertical direction from the inside of the part 122 , and the vertical fitting part 13 is an inner horizontal part 133 extending in a horizontal direction from the inside of the vertical part 132 . ) may be included.
