Abstract: The present invention relates to a safety blind that operates without a cord. More specifically, there is no danger of safety accidents because a lifting cord inserted into a fabric tube of a leather cord is not exposed to the outside, the lifting and tilting operation of an entire slat can be easily and simply performed by operating a lower slat, and a driving unit can be applied to Venetian blinds, roll blinds, and various blinds.

Abstract: The present invention relates to a device for preventing bending of a lower rotary rod and wrinkling of fabric in double blind without a string. More specifically, while a lower case is moved downwardly by the force of a handle portion (250) being pulled, a pair of rollers and a lower rotary rod are rotated. The rollers having a smaller diameter than the lower rotary rod prevent the lower rotary rod from rising and at the same time offset the load while rotating in close contact with double fabric (240), and thus prevent bending of the lower rotary rod or wrinkling of the fabric.

Abstract: A spring pre-tensioning device for a roll blind is provided. The pre-tensioning device includes a rotation shaft including a threaded part, with a restraining protrusion provided on the threaded part, and a locking groove. The pre-tensioning device also includes a restraining nut engaged with the threaded part of the rotation shaft, and disposed on the restraining protrusion, so as to prevent the restraining nut from moving further forward; a restraining body provided with a shaft insertion hole therein, and provided with a locking protrusion and a locking clip and a spring. The restraining body is fitted over the outer circumferential surface of the rotation shaft and is fixedly connected to the spring is rotated to apply a predetermined pretension value to the spring, and is engaged with the restraining nut that is prevented from forward rotation, thereby restraining pretension of the spring.

Abstract: The present invention relates to double fabric blinds and, more particularly, to a device for adjusting a fabric angle of the double fabric blinds, which is capable of finely adjusting an degree of openness of a front sheet, wherein a plurality of balls are sequentially held in a holding groove, e.g., as four or eight balls, inserted into an insertion groove of a rotation component, wherein the plurality of balls are rotated in a guide groove of a stopper by approximately 90 degrees or 45 degrees, thereby improving safety and omitting the use of a conventional string.

Abstract: Disclosed is a one cord blind that has a simplified structure enabling it to be easily manufactured, prevents a safety accident by not using a ball chain, makes an interior design neat and enables a roll screen to move upward and downward by a rotating cord or hands, so that the upward and downward operations can be easily made.

Abstract: A child-resistant roller blind apparatus is provided in which a roller blind is operated only when a safety hook of a cord or a ball chain, which is coupled with an elastic gear, is fixedly mounted after being tightened, so that a safety accident by the ball chain is completely prevented, improving the safety.

Abstract: An automatic winding device of a roll screen is disclosed. A screen is automatically rolled up when a user pulls a ball chain down and the screen is automatically stopped when the user just releases the ball chain, to thereby adjust a height of the screen simply and easily. A lower end of the screen is prevented from colliding with the winding device when the screen is rolled up, to thereby create a silent and comfortable indoor environment.
