Or the hemispherical powder 51 may be the second grab 20 and both the first and second grab 10 and 20 may be composed of the hemispherical powder 51. [

(In the following description, the term 'hemispherical shape' means a shape in which a cross section can be a semicircular shape, and is not necessarily limited to a half-sphere shape, but is a selection for helping a clear understanding of a shape.

Also, the expression 'prototype' is additionally a naming choice for a clear understanding of its form.)

The hemispherical powder 51 constitutes a circular clamping portion 55 or a hemispherical clamping portion 56 which surrounds the first or second scroll bar 3 according to a shape pivoting about the hinge pin 53.

The hemispherical powder 51 has a structure in which two powder particles are connected with the hinge pin 53 as an axis. For convenience of explanation, the first hemisphere 51A is arranged on the left side and the first hemisphere 51A is arranged on the right side 2 hemisphere 51B.

The first and second grips 10 and 20 have the same shape. This is only an example of the present invention. In the detailed description of the present invention, the first and second grips 10 and 20 will be described. Is judged to be sufficiently inferable from the first grab 10 if a person skilled in the art can understand it.

As shown in FIG. 4, the hemispherical powder 51 includes first and second binding portions 511 and 512 formed at the ends of the first hemisphere 51A,

And a third binding portion 513 formed on the second hemisphere 51B and arranged and coupled between the first and second binding portions 511 and 512. [

In addition, the first through third binding portions 511, 512, and 513 are formed to have a hinge pin 53 penetratingly connected to each other, as shown in FIG.

The first grab 10 has a fourth binding portion 514 formed on the first hemisphere 51A and a second binding portion 514 formed on the second hemisphere 51A on the side of the connecting portion where the first grab 10 and the second grab 20 are connected And a fifth binding portion 515 formed on the hemisphere 51B and engaged with the fourth binding portion 514. [

The hinge pin 53 penetrates through the fourth binding portion 514 and the fifth binding portion 515 in addition to the first to third binding portions 511, 512 and 513, As shown, the first and second grips 20 and 20 are passed through the first and second grips 10 and 20 to engage the first and second grips 20 and 20, respectively.

When the hemispherical powder 51 is deformed by the hemispherical clamping part 56, the recessed grooves 30 are formed under the upper hinge pin 53 so that the recessed grooves 57 of the hemispherical powder 51 are combined.

In forming the hook 30 to be electrically connected,

In addition, when the circular clamp 55 is formed, the outer peripheral surface of the first or second scroll bar 2 or 3 can be gripped to hold the roll screen S for storage, transportation, or the like.

Preferably, the first and second grips 10 and 20 are all provided with a circular clamp 55,

More preferably, the first grip 10 is a hemispherical clamp 56 and the second grip 20 is a circular clamp 55 for gripping.

Fig. 5 [A] shows a fourth embodiment of the present invention.

According to the fourth embodiment,

The first grip 10 includes a hook 61 and first and second bent portions 62 and 63 connected to the hook 61 and inserted into the opening of the first scroll bar 2.

5 (A), the first bent portion 62 is inserted into the first scroll bar 2 through the opening of the first scroll bar 2,

The second bending part 63 is connected to the first bending part 62 in the first scroll bar 2 perpendicularly.

Since the first grip 10 having the first bent portion 62 and the second bent portion 63 has a joining point inside the first scroll bar 2, more rigid engagement is ensured, There is an excellent advantage in terms of 'bonding stability'.

Next, a fifth embodiment of the present invention is shown in Fig. 5 [B], and according to the fifth embodiment,

The first grip 10 includes a first hinge portion 71 provided at a connection point between the hook 61 and the first bending portion 62,

And a second hinge portion 72 provided at a connection point between the first bent portion 62 and the second bent portion 63. [

It is assumed that the first grip 10 like the fourth embodiment has an opening portion formed in the first scroll bar 2 and a receiving space provided on the inner side thereof,

When manufacturing roll sills (S) of various sizes, it is difficult to make a space for the inside of the room (the internal space is not as strong as the external space), and therefore, The engagement with the first scroll bar 2 must be maintained by the force of clamping the outer peripheral surface of the first scroll bar 2.

Accordingly, the first bent portion 62 and the second bent portion 63 are provided and as shown in Fig. 5 [B]

The first grip 10 can effectively clamp the outer circumferential surface of the first scroll bar 2, and at the same time, the electric connection stability can be achieved.

The first grip 10 includes a first grip portion 81 surrounding the outer circumferential surface of the first scroll bar 2, a second grip portion 82 surrounding the inner circumferential surface of the first scroll bar 2, and a first grip portion 81 And a support 83 connected to the second gripper 82 and inserted into the opening of the first scroll bar 2.

In the fourth embodiment, the 'engagement stability' is sufficiently ensured, but the swinging phenomenon due to the clearance between each bending portion and the space for accommodating the first scroll bar 2 is very uncomfortable in the mounting of the roll screen S This can be a disadvantage.

The first grip portion 81 and the second grip portion 82 and the support portion 83 are provided to have a first grip portion 81 corresponding to the outer peripheral surface of the first scroll bar 2,

A second grip portion 82 connected to the second grip portion 82 through the support portion 83 and corresponding to the inner circumferential surface of the first scroll bar 2,

The first scroll bar 2 is positioned between the first grip portion 81 and the second grip portion 82 without a clearance to provide 'joint stability'.

In the fourth and sixth embodiments described above, only the first grip 10 has been described, but it is also applicable to the second grip 20, and any person skilled in the art can understand and infer the method.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the details of the illustrated embodiment, but may be modified and changed without departing from the scope and spirit of the invention. Substitutions should be construed as falling within the scope of protection of this invention.
