In this embodiment, the sheet member 100 includes a sheet material main body 110 and a rotatable guide protrusion 120. [

The upper end portion of the sheet material main body 110 of this embodiment is wound on the winding drum.

The sheet material main body 110 may be made of various synthetic resin materials known in the art, for example, a PVC tarpaulin material.

A plurality of engaging holes 111 are formed along both side edges of the sheet material main body 110 and a rotatable guide protrusion 120 is provided for each engaging hole 111. [

2 and 3 show only one side edge of the sheet material main body 110, and the other side edge has a coupling hole 111 formed in the same shape and a rotatable guide protrusion 120 is provided.

The engaging hole 111 of this embodiment is formed in a circular shape. The shape of the coupling hole 111 is for smooth rotation of the rotatable guide protrusion 120 described later.

However, according to the embodiment, the shaft member is engaged with the engaging hole 111, and if the first and second spherical rotary members are rotatably coupled to the shaft member, the engaging hole 111 may have a polygonal shape.

The rotatable guide protrusion 120 of the present embodiment is constituted by the first guide projection member 121, the second guide projection member 122, the first washer ring 123 and the second washer ring 124 .

The first guide projection member 121 is composed of a first spherical rotary member 121a and an inner shaft member 121b.

The inner shaft member 121b is formed to penetrate the engaging hole 111. The first spherical rotary member 121a is integrally formed at one end of the inner shaft member 121b and the inner shaft member 121b And extends from the first spherical rotational member 121a toward the second spherical rotational member 122a.

The first spherical-shaped rotary member 121a has a shape protruding in a spherical shape toward the direction away from the sheet material main body 110. Such a spherical protrusion form prevents the rotatable guide protrusion 120 from being separated from the sheet guide portion 11 due to the protruding height of the first spherical rotational member 121a and the contact with the sheet guide portion 11 The first spherical-shaped rotary member 121a can be easily rotated while the first spherical-shaped rotary member 121a is moved away from the sheet guide portion 11 when the sheet member main body 110 receives a very strong force Thereby protecting the sheet member main body 110.

At the other end of the inner shaft member 121b, a coupling step 121b-1 protruding in a radial direction is formed.

The second guide projection member 122 is composed of a second spherical rotary member 122a and an outer shaft member 122b.

The outer shaft member 122b is formed to penetrate through the coupling hole 111 and the through hole 122b-1 for the inner shaft member 121b to be inserted therethrough is formed along the inside of the outer shaft member 122b .

The second spherical rotary member 122a is integrally formed at one end of the outer shaft member 122b and the outer shaft member 122b is formed integrally with the first spherical rotary member 121a .

The second spherical rotating member 122a has a shape protruding in a spherical shape toward the direction away from the sheet material main body 110. [

Such a spherical protrusion form prevents the rotatable guide protrusion 120 from being separated from the sheet guide portion 11 due to the protruding height of the second spherical rotating member 122a and the contact with the sheet guide portion 11 The second spherical rotary member 122a can be easily rotated when the sheet member main body 110 receives a very strong force while allowing the second spherical rotary member 122a to be easily separated from the sheet guide portion 11 Thereby protecting the sheet member main body 110.

In addition, the second spherical rotary member 122a is formed with a coupling stepped portion 122a-1 for engaging the coupling step 121b-1 of the inner shaft member 121b.

The engaging step 121b-1 of the inner shaft member 121b of the first guide projection member 121 passes through the through hole 122b-1 of the second guide projection member 121 and the outer shaft member 122b, So that the first guide protrusion member 121 and the second guide protrusion member 121 are prevented from being separated from each other while being caught by the engaging jaw catching portion 122a-1.

In addition, the insertion through-hole structure of the inner shaft member 121b and the outer shaft member 122b allows the first spherical rotary member 121a and the second spherical rotary member 122a to be spaced apart from each other by a predetermined distance, The guide projecting members 121 and 122 can be smoothly rotated.

That is, the inner shaft member 121b and the outer shaft member 122b of this embodiment are a type of shaft member that penetrates through the engaging hole 111.

A first washer ring 123 is inserted between the first spherical rotational member 121a and the sheet material main body 110 and a second washer ring 123 is inserted between the second spherical rotational member 122a and the sheet material main body 110. [ 2 washer ring 124 is inserted.

The first and second washer rings 123 and 124 prevent the first and second spherical rotary members 121a and 122a from coming into contact with the sheet member main body 110, 121a, and 122a.

The first joining reinforcing projections 123a protrude from the surface of the first washer ring 123 facing the sheet member main body 110 and the first joining reinforcing protrusions 123a protrude from the sheet member main body 110 of the second washer ring 124 A second coupling reinforcing protrusion 124a is formed to protrude therefrom.

The first and second coupling reinforcing projections 123a and 124a allow the first and second washer rings 123 and 124 to be more tightly coupled to the sheet member body 110, Thereby preventing the sheet member 110 from being detached from the sheet material main body 110.

The operation of this embodiment will be described with reference to Figs. 2 to 3. Fig.

A support 10 is provided on both sides of the sheet material 100 and a sheet guide part 11 for guiding the lifting and lowering of the sheet material 100 is provided on the support 10.

The guide protrusion 120 of the sheet material 100 is inserted into the sheet guide part 11 to guide the sheet material 100 smoothly up and down.

The rotatable guide protrusion 120 basically serves to prevent the edge of the sheet member 100 from being detached from the sheet guide portion 11. [

The rotatable guide protrusion 120 of the present embodiment rotates when the rotatable guide protrusion 120 is brought into contact with the sheet guide portion 11 when the sheet material 100 is moved up and down, Thereby minimizing the friction caused by the friction.

Particularly, when the first guide protrusion member 121 and the second guide protrusion member 122 rotate, the rotatable guide protrusion 120 of the present embodiment does not directly contact the sheet member main body 110, It can be rotated while being in contact with the ring 123 and the second washer ring 124, thereby enabling smooth rotation.

As such, the rotatable guide protrusion 120 is rotated upon contact with the sheet guide portion 11 to minimize the movement resistance due to friction, and minimize damage due to friction.

On the other hand, although the present embodiment shows inner and outer shaft members 121b and 122b as a shaft member, it is sufficient that the shaft member penetrates through the engaging hole 111. According to the embodiment, A spherical rotating member may be rotatably provided.
