Description

Blinds

The shutter in this case, especially an invention aiming at the user who wants to open or close the shutter, only needs to operate the linkage rod to move up and down to synchronize the angle of all the hollow blades.

According to the domestic new type No. 358515 "Pitch Adjustable Blind Structure", as described in the first preferred embodiment of the patent specification: the pitch adjustable blind structure is made of plastic foam material, which includes a frame It consists of a positioning shaft, several louver plates and a linkage rod. Wherein, the frame system is composed of a first fixing piece, a second fixing piece, a third fixing piece, and a fourth fixing piece to form a frame body of an appropriate size, and there are several on the inner wall surfaces of the first fixing piece and the second fixing piece Shaft hole; the third fixing piece is provided with a slot.

The positioning rotating shaft is integrally formed, which is provided with a first shaft member and a second shaft member, and the first shaft member can be placed in the shaft hole of the frame; and the first shaft member and the second shaft There is a baffle between the pieces, and the baffle touches the inner wall surface of the first fixing piece and the second fixing piece, so that the distance between the two pieces can be fixed.

A fixed hole is provided on both sides of the louver plates, and the fixed hole can be fixed with the second shaft member of the positioning rotating shaft, and is a tight fit, so that there are several hundred plates on the frame body; A first hook is fixed at a suitable place in the center of the louver plate.

The linkage rod is an elongated body with a plurality of second hooks on a wall surface; the second hook is coupled with the first hook of the louver plate, so that the linkage rod can simultaneously drive several louvers The board opens and closes.

In use, the user only needs to grasp the linkage lever with his fingers to move up and down, and the whole blade can be rotated to adjust its angle. When the linkage lever moves upward, the upper end of the linkage lever will enter the slot. The entire set of blades is completely closed, and the author can assemble more than two pieces according to user needs.

The above-mentioned conventional blinds, although the deflection angle of the whole group can be adjusted at the same time by operating the linkage rod; however, due to its entire pitch-adjustable blind structure, it is mainly made of plastic foam material. The size must meet the requirements of the installer to guide its entire shutter structure, especially for large-sized shutters, whether it is the frame or the number of louver plates. At the time of initial manufacture, it manufactures the frame and The mold cost of the louver plate is quite high; secondly, the linkage rod and each louver plate are only nailed and hooked together with the hook, so that after a period of use, these hooks will be easy to loose The louver plate is made of plastic foam, and the louver plate cannot be nailed at the position where the nail is provided and then a new hook is re-nailed, which causes the linkage rod to fail to synchronize the blade row angle. Deflectors, all of which need to be improved.

In view of the fact that the traditional blinds can simultaneously adjust the deflection angle of the entire group by operating the linkage rod, but the mold cost of the structure manufacturing is quite high, the linkage rod and each louver plate only use the hook The nails are set and hooked together, so that after a period of use, these hooks will easily loosen the various defects caused by the drop, and then the blinds of the present invention are developed.

To achieve this object, the present invention provides a louver comprising: a linkage rod, angle adjustment clips, hollow blades, two frame bars, and a frame; the angle adjustment clips are integrally connected by the linkage rod, and Each angle adjusting clip is elastically connected with each hollow blade, and the ends of each hollow blade and its blade cover are set from the outer side of the two frame strips to the upright surface due to the combination of the two frame strips. The coupling hole penetrates, and the rear section of the coupling element is provided with a threaded section, and the front section is provided with a smooth cylinder, so that the rear section of the coupling element is locked with the coupling hole provided on the two frame strips, which is a smooth cylinder front section system The perforations and hollow leaves that extend into the center of the blade cover The sleeve holes provided at both ends of the sheet, so that although the ends of each hollow blade are limited between the two frame strips, both ends can maintain a free rotation state with the front section of the coupling element; therefore, they should be opened or closed When the louver is provided, it only needs to move up and down by operating the linkage rod to achieve the effect of synchronously driving all the hollow blades for angular deflection.
