Description

Projection Screen Roll Screen {Roll Screen}

The present invention relates to a video projector, a presenter, and a screen that can be used for light blocking purposes, and more particularly, a roll support that can be installed on a wall as well as an improved roll support to perform a roll-proofing and rotation of the roll without shaking. It's about the roll screen.

In general, screens are mainly used for light blocking purposes. Recently, screens are frequently used as video equipment such as OHP, video projector, and imager according to the spread of image culture and multimedia education.

In such a situation, the screen according to the prior art wears the roll supporting portion that supports the screen and gives a rotational force as the frequency of use increases, causing vibration or roll wrinkles during roll rotation, and even rolls. Due to the failure of the support, there was a problem such that the roll rotation is impossible.

In addition, in the case of the exposed screen according to the prior art there has been a problem that inhibits the aesthetics of the room as the screen is exposed and fixed to the outside.

The present invention was devised to solve the problems of the prior art as described above, and it is possible to increase the reliability of the rotation of the roll even after long-term repeated use, and even if installed on the wall projection screen roll screen is removed the elements that hinder the aesthetics of the room The purpose is to provide.

The technical idea pursued by the present invention is to construct a projection film roll screen that can be expected to be reliable for the rotation of the roll even after repeated use for a long time, and to constitute a projection film roll screen that can be installed on the wall.

To this end, the present invention is a roll 203, the screen is wound or unwinded, the body 201 incorporating the roll 203, the support for supporting the roll 203, the rolling roll for rotating the roll 203 208 and fixing brackets 206a and 206b capable of fixing the body 201 to a wall.

Hereinafter, the projection film roll screen according to the present invention through a preferred embodiment will be described in more detail.

This embodiment relates to a wall-mounted projection screen roll screen according to the present invention.

EXAMPLE

1 to 3 will be described in more detail the configuration of the wall-mounted projection film roll screen.

As shown in FIG. 1, the shape of the roll 203 is hollow, the protrusion 215 is formed on the inner surface thereof, and the screen 211 is wound on the roll 203 as described above. .

At the end of the screen 211, the screen 211 is held flat when the screen 211 is released. When the screen 211 is wound, the screen 211 is rolled into the body 201. The tension holding rods 212 which can be prevented are connected, and both sides of the tension holding rods 212 are coupled to the tension holding rod caps 213a and 213b which can prevent the screen from being separated.

The roll 203 wound around the screen 211 has a polygonal shape and is inserted into the body 201 having one side opened. As shown in FIG. 1, the screen 211 has a structure that can be drawn out from the inside of the body 201 along the drawing line 214 that is opened at one lower side of the body 201.

As described above, both sides of the body 201 having the roll 203 wound around the screen 211 are configured to support the roll 203 and to rotate the roll support 203.

The roll support is a feature of the present invention, as shown in FIGS. 1 and 2, the roll support is a structure that is coupled to both sides of the body 201, and can only absorb the rotational force generated in the roll 203. , A first roll side supporting the roll 203 and a roll roll 203 coupled to the other side of the roll 203 to which the roll 203 is inserted and mounted to impart rotational force to the roll 203. It is comprised by the 2nd support side provided with).

As shown in FIG. 1, the first support side has a roll cap 204 inserted and mounted in the roll 203, and a through hole 218 is formed in the roll cap 204 to allow the shaft rod 205 to pass therethrough. It is a structure that can be.

In addition, when the rotation force is applied to the roll 203 by the aforementioned rolling roll 208 as the bearing 202 is coupled to the shaft 205, the roll cap 204 and the shaft ( 205 is a structure that is rotatable.

Semi-circular key grooves 216a and 216b are formed at one side of the roll cap 204 and the rolling roll 208, so that the protrusion 215 formed inside the roll can be engaged.

Therefore, when a rotational force is generated in the rolling roll 208, the roll 203 and the roll cap 204 are configured to transmit a more reliable rotational force.

In addition, the shaft bar is provided with a settling jaw 219, the roll cap 204 coupled to the shaft rod 205 as the settling jaw 219 is placed in a settling groove (not shown) formed in the bearing 202, Rotation of the roll 203 coupled to the roll cap 204 is a structure that can be obtained on the same axis without being spaced apart.

The first support side and the second support side configured as described above are finished with finishing brackets 210a and 210b, and the bearing support bracket 207a is fastened to the first support side finishing bracket 210a by using a bolt. The bearing 202 is fastened to the bearing support bracket 207a by using a bolt.

Similarly, the rolling roll cap 209 coupled to the rolling roll 208 is also fastened to the bearing supporting bracket 207b using a bolt, and the bearing supporting bracket 207b is attached to the second supporting side closing bracket 210b. It is a structure that is fastened to the closing bracket (210b) with a bolt.

For reference, the electric power supply line 220 is connected to the electric roll 208, and the electric power supply line 220 sequentially rotates the electric roll cap 209, the bearing support bracket 207b, and the closing bracket 210b. It penetrates through and is discharged to the outside so that power can be supplied.

The fixing brackets 206a and 206b for fixing the projection screen roll screen to the wall are fastened to the finishing brackets 210a and 210b having the above-described configuration by using bolts to be assembled.

In the finishing brackets 210a and 210b of FIG. 1, a plurality of bolt balls into which bolts can be inserted are formed, and the fixing brackets 206a and 206b may be coupled thereto.

The fixing brackets (206a, 206b) is configured of a 'b' shape, the inner surface is bolted to abut the finishing brackets (210a, 210b), the outer surface abuts the edge portion of the wall can be fixed fastening It is a structure (refer FIG. 3).

Referring to Figure 3, the wall-mounted projection film roll screen 200 according to the present invention is a structure that can be fixed fastening using the fixing brackets (206a, 206b) in the corner portion of the wall sealing abutment.

As described above, according to the present invention, the reliability of the rotation of the roll is solved even by prolonged repeated use by improving the shape of the bearing and the shaft.

In addition, by providing a wall-mounted projection screen roll screen that can be installed at the corner where the wall member sealing meets without damaging the aesthetics of the room, it is expected that the effect can be applied to a screen for the purpose of screening or light blocking.
