Abstract

A fast-dismantling safe blind includes a rod, a shed cloth and at least a lift cord. The rod includes an end stop; the shed cloth, which is fixed on the rod, has male fastening tapes; and the lift cord has a movable end and a fixing end which passes through the end stop of the rod. Female fastening tapes are on the fixing end, opposite to the male fastening tapes on the shed cloth, and a tail end of the fixing end is fixed at the tail female fastening tape, allowing the fixing end of the lift cord to be fixed on the shed cloth by fastening with the male and female fastening tapes. Therefore, through fastening with the male and female fastening tapes, the shed cloth can be quickly dismantled from the lift cord, thus providing a blind with a better safety feature.

Description

BACKGROUND OF THE INVENTION

a) Field of the Invention
The present invention relates to a fast-dismantling safe blind and more particularly to a blind which is provided with a better safety feature and can be dismantled and re-assembled quickly.
b) Description of the Prior Art
Referring to FIG. 1 and FIG. 1 a, it shows schematic views of a conventional blind. As shown in the drawings, the conventional blind includes a rod A and a shed cloth B, wherein the rod A is provided with an end stop C and two lift cords D which pass through the end stop C respectively. One end of the lift cord D is a fixing end D1 to be connected with the shed cloth B and the other end is a movable end D2. The shed cloth B is provided with plural rings B1, whereas the two lift cords D pass through a part of the rings B1 and are fixed at the ring B1 at a tail end.
Accordingly, through extension of the movable end D2 of the lift cord D and an operation of the end stop C, the shed cloth B can be driven to ascend and descend.
When assembling the aforementioned blind, the fixing end D1 of the lift cord D is first made to pass through the end stop C and the rings B1 on the shed cloth B, followed by being fixed at the ring B1 at the tail end. However, as the rings B1 are fixed on the shed cloth B by sewing, when the fixing end D1 of the lift cord D passes through the rings B1 and is fixed at the ring B1 at the tail end, the shed cloth B will not be able to be separated with the lift cords D immediately and the lift cords D which are fixed on the ring B1 at the last ends must be untied that the lift cords D can be dismantled from the shed cloth B.
Therefore, when a child or an adult is using the aforementioned blind, he or she will be easily hooked on a neck by the lift cords D if the blind is not used carefully and the shed cloth B will be often unable to be dismantled from the lift cords D at once, thereby causing an accident to the child and also becoming a hidden risk to the child at a home.
Therefore, to solve the aforementioned issues, the present invention provides a blind which can be dismantled quickly and is provided with a better safety feature, so as to prevent from causing an accident to a child.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a blind which is provided with a better safety feature and can be dismantled and re-assembled quickly.
To achieve the aforementioned object, the present invention includes a rod, a shed cloth and at least one lift cord, wherein the rod is provided with an end stop; the shed cloth is fixed on the rod and is provided with plural male fastening tapes; and the lift cord is provided with a movable end and a fixing end which passes through the end stop of the rod, with plural female fastening tapes being provided on the fixing end, opposite to the male fastening tapes on the shed cloth, and a tail end of the fixing end being fixed at the tail male fastening tape, allowing the fixing end of the lift cord to be fixed on the shed cloth by using a fastening effect between the male fastening tapes and the female fastening tapes.
Accordingly, through the fastening effect between the male fastening tapes and the female fastening tapes, the shed cloth and the lift cords can be dismantled and re-assembled quickly, thereby providing a blind with a better safety feature.
In addition, the other characteristic of the present invention is that when a weight of the shed cloth changes, the plastic rings of a conventional blind on a market should be replaced in order to support the weight of the cloth; however, in the present invention, it is not necessary to replace the fastening tapes.
To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIG. 2 and FIG. 2 a, it shows schematic views of a blind of the present invention. As shown in the drawings, the blind comprises a rod 10, a shed cloth 20 and two lift cords 30, wherein the rod 10 is a rectangular bar and is provided with an end stop 11 (no further description is disclosed, as it is a conventional element); additionally, the rod 10 is also provided with two positioning rings 12.
An end of the shed cloth 20 is fixed on the rod 10 and the other end is suspended below the rod 10. Additionally, the shed cloth 20 is provided with plural male fastening tapes 21 and in the present embodiment, the shed cloth 20 is provided with two rows of the male fastening tapes 21.
Each of the two lift cords 30 is provided respectively with a movable end 31 and a fixing end 32. The movable end 31 is sheathed with a tassel 33 and the fixing end 32 passes through the end stop 11 and the positioning ring 12 of the rod 10, respectively. Furthermore, plural female fastening tapes 34 are provided on the fixing end 32, opposite to locations of the male fastening tapes 21 on the shed cloth 20, and a tail end of the fixing end 32 is fixed on the tail female fastening tape 34.
When assembling, an end of the shed cloth 20 is fixed on the rod 10, and then the fixing ends 32 of the two lift cords 30 are made to pass through the end stop 11 and the positioning rings 12 of the rod 10, respectively. After the fixing ends 32 of the two lift cords 30 have passed through the plural female fastening tapes 34, the tail ends of the fixing ends 32 are fixed on the tail female fastening tapes 34, allowing each female fastening tape 34 to move on the fixing end 32 of the lift cord 30. Finally, by fastening together the female fastening tapes 34 and the male fastening tapes 21 on the shed cloth 20, the fixing ends 32 of the lift cords 30 can be fixed on the shed cloth 20, further enabling the shed cloth 20 to ascend and descend on the rod 10 through extension of the movable ends 31 of the lift cords 30. Besides, the movable end 31 of the lift cord 30 is sheathed with the tassel 33 which facilitates a user to pull.
Referring to FIG. 3 and FIG. 4, it shows schematic views of partial operations of the blind of the present invention. As shown in the drawings, through fastening together the female fastening tapes 34 on the lift cords 30 and the male fastening tapes 21 on the shed cloth 20, the male fastening tapes 21 can be quickly assembled with and dismantled from the female fastening tapes 34, further allowing the lift cords 30 to be quickly separated with the shed cloth 20. Accordingly, when a child is using the blind and accidentally hooks the lift cords at a neck, the lift cords 30 and the shed cloth 20 can be separated through the feature that the male fastening tapes 21 can be quickly assembled with and dismantled from the female fastening tapes 34, thereby preventing from an accident and improving safety of use to the child.
Finally, referring to FIG. 5 and FIG. 5 c, it shows schematic views of a second implementation configuration of the blind of the present invention. As shown in the drawings, the female fastening tapes 34 on the lift cords 30 can be further formed in a shape of a ring, allowing the lift cords 30 to be transfixed in the female fastening tapes 34 easily. The female fastening tapes 34 can also easily and quickly move along the lift cords 30 to be actually fastened with the male fastening tapes 21 on the shed cloth 20. In addition, the movable ends 31 of the two lift cords 30 can be fixed on a second tassel 35 at a same time, so as to form a linking relationship to the two lift cords 20 by pulling the second tassel 35, thereby achieving a function of adjusting a height of the shed cloth 20.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
