End-weight device for a horizontal fabric blind

Abstract

An end weight device for horizontal fabric blind includes the front and rear meshed screens fixed to a winding rod rotatably installed inside a head rail. The front and rear meshed screens are secured to each edge of a plurality of shield slats, so that sunlight can be shielded. While the plurality of shield slats is maintained in a level state, the blind allows entering the sunlight and venting air. The meshed screens are tensioned responding to pull the operating string. Since a plurality of shield slats are maintained in a level state with the front and back meshed screens due to the end weight device, the front and rear meshed screens are not separated from each other.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(9) Hereinafter, the end weight device for the horizontal fabric blind of the preferred embodiment of the present invention will be described in great detail with reference to the accompanying drawings.

(10) However, the purpose of accompanied drawings is easily described the present invention. The scope of the present invention is not limited to the scope of the accompanied drawings. It will be appreciated those who skilled in the art.

(11) First of all, it should be noted that the same components or parts in the drawings have the same reference numerals as much as possible. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted so as not to obscure the gist of the invention.

(12) As shown in the drawing, the end weight device (100) for a horizontal fabric blind of the present invention is provided that: a winding rod (not shown) is rotatably installed inside of the head rail (50) of the horizontal fabric blind (30). A plurality of shield slats (80) is integrally and fixedly attached to the front and rear meshed screens (60, 70) with constant intervals. Both ends of the shield slats and the meshed screens (60, 70) are integrally woven each other for blocking the sunlight. A plurality of shield slats (80) and both of the meshed screens (60, 70) allows venting the air and admitting the sunlight at the level state of the shield slats (80) by operating string. Due to shifting the weight, a plurality of the shield slats (80) alters to the vertical state respect to the front and rear meshed screens (60, 70). The front and rear meshed screens (60, 70) are not separated by automatically maintaining the level state of the shield slats (80), each other. Thereby, it will prevent the leakage of sunlight through the plurality of shield slats (80). Also, it will prevent a swinging while the winding rod is winding by shifting the weight to one-side.

(13) In other words, the end weigh device (100) for a horizontal fabric blind according to the present invention has a structure as shown in FIG. 3 to FIG. 6. It is consist of the front and rear meshed screens (60, 70), a plurality of the shield slats (80) is integrally woven to each end-side of the front and rear meshed screens (60, 70) with constant intervals for blocking the sunlight. A shielding portion (40) of the horizontal fabric blind (30) is consisted of the plurality of the shield slats (80) being integrally attached with the front and rear meshed screens (60, 70). A fixing plate (110) forming a bar-shape is integrally connected to the front and rear meshed screens (60, 70) by the fixing means, such as both-side tapes. First and second fastening sectors (131, 132) are formed at each end-side of the fixing plate (110), so that each end of the fixing plate (110) can be attached to the front and back meshed screens (60, 70), respectively. The center portion of the fixing plate (110) has formed a downward curvature portion (133). An end of the first fastening sector (131) is outwardly extended. An end weight device (130) has provided an eccentric weight portion (134) so that the end weight device (130) will respond to the pulling of the operating string (90) to rotate the shield slats (80) for automatically maintaining the level state, with respect to the front and rear meshed screens (60, 70) by the eccentric weight. Both edge-side of the end weight device (130) forms clamping portion to fixedly insert the front and rear meshed screens (60, 70), respectively. And, a cover member (150) is provided to prevent the detaching the fixing plate (110).

(14) Herein, the eccentric weight portion (134) of the end weight device (130) has formed a longitudinal cavity (134a) for inserting a weight member (170), so that the end weight device (130) can increase the eccentric weight along the longitudinal direction,

(15) Additionally, the end weight device (130) is preferably made of aluminum or resin (resin) to form an eccentric weight.

(16) On the other hand, the end weight device (130) of the horizontal fabric blinds according to the present invention, the end weight device (130) would be formed as a single body as shown in FIG. 3 to FIG. 6, but it is not limited thereto. As shown in FIG. 7, the left and right edges of the end weight device (130) could be attached and detached by adopting a sliding method to the front and rear meshed screens (60, 70), respectively. A cover member as shown in FIG. 8, can be inserted to be fixed at both edges of the end weight device (130).

(17) The end weight device of the horizontal fabric blind according to the present invention: when a user pulls the operating string, the shielding portion (40) of the horizontal fabric blind (30) will fully deployed as shown in FIG. 3, while the winding rod installed inside of head rail is actuating the shielding portion (40) of the horizontal fabric blind.

(18) At this moment, the plurality of light-shield slats (80) are maintained in a horizontal state as shown in FIG. 3, it will allow to admit the sunlight and air is ventilating.

(19) Further, a user pulls the operating string, the end weight device (130) of the horizontal fabric blind according to the present invention is shifted by the eccentric weight portion (134) to face the wall as shown in FIG. 6.

(20) Thus, the end weight device (130) automatically maintains a straight line with respect to the front and rear meshed screens (60, 70).

(21) Because the end weight device (130) is closely aligned to the front and rear meshed screens (60, 70), the front and rear meshed screens (60, 70) would be flat without a space.

(22) Accordingly, the plurality of shield slats (80) attached between the front and rear meshed screens (60, 70) with predetermined intervals will be overlapped each other and maintained the vertical state, so that the sunlight is blocked by the light-shielding slats (80).

(23) The foregoing description is merely illustrative of the technical idea of the present invention. Further, the various changes and modifications may be made easily by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention. The scope of the technical idea of the present invention is not limited by these embodiments. It is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
