And the state in which the rope is pressed.

Generally, the blinds are formed by dropping a loop-shaped blind rope R downward to raise and lower the sheet.

The present invention comprises a plate-like guide (100) configured to be inserted and raised by the blind rope (R). In other words, it is structured so as to be sandwiched between the two ropes R so as to be vertically transported, and to cover the space between the two ropes R, so that the head of the infant can not pass.

And a braking unit 200 mounted on the guide 100 for pressing and releasing the rope R. [ Therefore, when raising and lowering the sheet by rotating the rope R, the guide 100 is raised and braked, and after the rope R is used, the guide 100 is lowered by releasing the braking.

The guide 100 is, for example, a plate-like body 110 having a shape interposed between the ropes R. In addition, tubes (120) are formed on the left and right sides of the body 110 to allow the rope R to pass therethrough. Thus, it is possible to slide up and down along the rope R, and the body 110 is configured to cover between the ropes R. [ In addition, a cut-out portion 123 configured to pass through the mutually opposing portions of the tube 120 and to expose the rope R is formed. A through hole 113 is formed in the body 110 so that the operation part 240 to be described later can be mounted. The through hole 113 is disposed between the two side incisions 123.

The bending portion 200 is configured to be capable of pressing and unbending a rope R mounted on the body 110 and exposed to the cutout 123. The bending portion 200 may be formed in a shape corresponding to the through- The rear cover 210 is configured to cover the rear surface of the cover 110. [ The front cover 220 is configured to cover the front of the body 110 to correspond to the rear cover 210. The front cover 220 is provided with a slot 223 which is vertically penetrated through the upper and lower walls and the button 230 exposed outward from the inside of the front cover 220 through the slot 223, . The button 230 is slidable upward and downward to press and release the rope R exposed through the cutout 123. The front cover 220 and the rear cover 210 And an operating portion 240 configured to pass through the through hole 113 is formed.

The operating portion 240 may include two pins formed on the front surface of the rear cover 210 and arranged side by side on both sides so as to pass through the through hole 113 and correspond to the cut- 241). A supporter 242 disposed on the front surface of the rear cover 210 and passing through the through hole 113 is positioned below the pin 241. The compression spring 243 is supported by the supporter 242 and is directed upward. As an example, the supporter 242 may be formed in a protruding block shape so that protrusions (not shown in the figure) sandwiching the compression springs 243 are further provided to prevent the compression springs 243 from being separated.

A lever 244 configured to push the rope R exposed through the pin 241 and pivoting toward the cutout 123 is formed. A pin 245 is formed in the lever 244 so as to pass through the inside of the portion through which the pin 241 is passed (opposite side of the cutout) and to be arranged on both sides of the rear surface of the button 230. That is, the lever 244 is formed with a pinhole Q through which the pin 241 of the rear cover 210 passes, and the pin (not shown) of the front cover 220 245 passing through the pinhole P is formed.

The pitch of the side fins 241 connected to the rear cover 210 is larger than the pitch of the side fins 245 connected to the front cover 220. [ Thus, when the button 230 is raised, the lever 244 pivots outward and passes through the cutout 123 to press the rope R. When the button 230 is lowered, the both levers 244 are broken So that it is separated from the incision 123. The button 230 is lifted by the compression spring 243 when the hook 249 is not caught by the latching groove 247 and the both levers 244 pass through the cut- .

And a protrusion 246 formed on a rear surface of the button 230 to press the compression spring 243 to be disposed below the pin 245. The protrusion 246 may be formed with a hole (not shown) into which the compression spring 243 is inserted to prevent the compression spring 243 from being separated from the protrusion 246.

The front cover 220 is formed with an engagement groove 247 formed at the lower side of the slot 223 on the inner side of the front cover 220, And a hook 249 formed therein. Therefore, when the button 230 is lowered and the hook 249 is hooked on the latching groove 247, the button 230 is prevented from rising.

The button 230 is an example in which the pin 245 and the protrusion 246 are formed on the rear surface and the hook 249 is formed on the lower end of the button 230. The hook 249 is formed on the inner surface of the front cover 220, A plate 231 sized to engage is constructed. Also, a block 235 formed on the front surface of the plate 231 and sized to be able to slide up and down through the slot 223 can be pushed by a finger. Accordingly, the button 230 is prevented from being detached from the slot 223 by the plate 231, and the block 235 can be pushed up and down.

In addition, since the unit 300 is formed to penetrate the rear cover 210, the body 110, and the front cover 220, the unit 300 can be easily assembled and disassembled.

That is, the rear cover 210 and the body 110 are provided with a pair of through holes 217 and 117, and protrusions 217 and 117 protruding from the rear surface of the front cover 220 corresponding to the pair of holes 217 and 117 227 are formed and a tab hole (not shown) is formed in which the piece 300 is fastened to the projection 227. Therefore, after the pieces 300 pass through the piece holes 217 and 117, they are inserted into the tapped holes and fastened.

The operation of the present invention with the above-described structure will be described with reference to FIGS. 8 and 9. FIG.

When the hook 249 is disengaged from the hooking groove 247, the compression spring 243 pushes the button 230 upward to rotate the lever 244 in the outer direction, So that the rope R is pressed. Therefore, the guide 100 is maintained in the braked state and is prevented from being conveyed along the rope R.

When the button 230 is lowered in this state, when the compression spring 243 is compressed and the hook 249 is caught by the latching groove 247, the lowered state of the button 230 is maintained, So that it comes out of the cutout 123 and releases the braking state. Therefore, the guide 100 can be conveyed along the rope R. [

Therefore, as shown in Fig. 3, when the blind braking mechanism 90 is lowered along the rope R, it covers the space between the ropes R, thereby preventing the head of the infant from passing through. Therefore, it is possible to prevent safety accidents such as suffocation or mental loss due to the child's neck being caught by the rope (R). 4, since the space between the ropes R is opened in the raised state, the seat can be easily lifted and lowered by holding the rope R and pulling it easily.
