Description

Invisible window

The invention relates to an invisible window, in particular to a cable that can be directly installed on a window or a balcony, or a steel cable installed in a frame with a sky bolt, so that the cable window can be quickly disassembled on a window or a balcony, and The wire rope fixing seat is provided with a screen window slot for installing screens to prevent mosquitoes and foreign objects from entering the room, and to improve the quality of living and the invisible window of the living safety.

In accordance with the conventional invisible window, such as the "wire rope protection structure" of Taiwan Patent No. M393567 (Application No. 099215543), a pair of oppositely disposed cable fixing seats (10) are provided in the cable protection structure; wherein the cable fixing seat ( 10) is formed by combining an L-shaped seat strip (11) with a cover (12), and with the use of a plurality of clamps (13), the steel cables (20) are equally spaced into a mesh surface; the L-shaped seat strip ( 11) The horizontal plane (112) is screwed to the building (30) such as a balcony or a wall. The vertical surface (111) provides a multi-array clamp (13) setting, and the clamp (13) is fixed by a fixed The bolt (131) is provided with two clips (132) screwed on the vertical surface (111); the vertical surface (111) is further provided with a plurality of screw seats (14), and the screw cover (15) is used to pass the cover (12) ) Locked to the screw seat (14).

However, please refer to Figures 2 and 3 of the conventional cable protection structure. Since the clamp (13) is mounted on the vertical surface (111) of the L-shaped seat strip (11), only one bolt (131) is used. The two clips (132) are screwed on the vertical surface (111), so when the cable (20) is wound around the upper and lower L-shaped strips (11), the clamp (13) is easy to be strong due to the cable. Deformation or breakage caused by pulling force, which affects the installation of the cable; then, when the L-shaped seat strip (11) and the seat cover (12) are locked to each other, the vertical surface of the L-shaped seat strip (11) is required (111 a screw seat (14) is arranged on the upper part, and a hole is formed at the upper end of the seat cover (12) corresponding to the position of the screw seat (14), so that the screw seat (14) is required when the seat cover (12) is locked After the perforation corresponds to the perforation of the cover (12), the screw (15) can be passed through the locking seat cover (12), and a protruding portion on the side of the upper end of the cover (12) will abut the screw seat (14). Therefore, when the screw (15) is locked to the screw seat (14), the screw seat (14) is bent at the position of the abutting projection, so that the screw seat (14) is deformed, and the screw (15) cannot be produced. The problem of locking the cover (12) and the screw seat (14); and the conventional cable protection structure cannot be installed Mounted screens, so mosquitoes can not stop the foreign invasion and the room, the mosquito and foreign matter to easily enter the room, affecting the quality of home life.

In addition, the "home security guard" of the Japanese Patent No. M354125 (Application No. 097220297) is provided with the blocks 111, 211 at the sides of the card portions 11, 21 for engaging the buckle portion. At 12, 22, the card portions 11, 21 and the buckle portions 12, 22 are combined and fixed. However, although the blocks 111 and 211 on both sides of the card portions 11 and 21 can quickly fix the card portions 11 and 21 and the buckle portions 12 and 22, the card blocks 111 and 211 and the buckle portions 12 and 22 need to be first fixed. After the separation, the card portions 11 and 21 and the buckle portions 12 and 22 can be separated. Therefore, when the card blocks 111 and 211 are separated, the card pieces 111, 211 or the card portions 11 and 21 are deformed or broken due to improper application. The card portions 11 and 21 and the buckle portions 12 and 22 cannot be combined and fixed, and the positioning device 1 cannot be smoothly installed. Moreover, the conventional house safety protection device cannot be installed with screen screens when installed, and thus cannot block mosquitoes and foreign objects. Invade the room, allowing mosquitoes and foreign objects to enter the room easily, affecting the quality of life at home. To this end, the inventors of the present invention have been studying the design and manufacturing experience of related products for many years, and have studied the shortcomings of the aforementioned conventionals to invent the present case.
