Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention belongs to the field of special means related to doors or windows, and relates to a feather guide plate (hereinafter referred to as a fin guide) used for furniture or architectural shutters. Used for manufacturing.

(Prior art) Fin guides conventionally used for shutters have fin mounting grooves dug for each fin guide, which limits the processing method and results in high processing costs. There is a drawback that the deviation of the groove pitch of the fin guide directly affects the misalignment of the fins.

(Problems to be Solved by the Invention) The present invention reduces machining costs by using the fin attachment groove as a through groove that is not restricted by the machining itself, and also provides a pair of symmetrical fin guides having the same groove. This is intended to eliminate misalignment of the fins with respect to the fin guide by manufacturing them all at once.

(Means for Solving the Problems) The present invention solves the above problems by forming a required number of grooves on one side of a long plate with a rectangular cross section.
A multi-stage excavation is made by penetrating both the front and back sides of the plate at a predetermined angle of inclination and a predetermined depth and width, and a back plate having the same height and width as the same side is superimposed on one side of the plate. The columnar body is pasted to form a columnar body, and the columnar body is cut into sections from the center between the left and right side surfaces, with the front and rear directions as cut planes.

(Function) Since the grooves penetrate from front to back, machining is easy, and even if pitch errors occur between the individual grooves, symmetrical grooves can be arranged in the fin guide by dividing the grooves left and right. Therefore, as long as the vertical reference planes of the left and right opposing fin guides are aligned, no misalignment will occur between the fins disposed horizontally in the groove.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. As shown in FIG. with an inclination angle of and a given depth and width, i.e.
The depth in this embodiment is approximately twice the depth when the end of the fin is inserted all the way and fitted horizontally, and as shown in FIG. Then, in the groove 2 arranged in this way, the plate 1 is
As shown in Fig. 2, on the opening surface 3 side on the right side of the The columnar body 5 shown in FIG. 3 is formed by overlapping and pasting back plates 4 having dimensions equal to the thickness of the plate body 1 in which the grooves 2 are left. Next, columnar body 5
A pair of bilaterally symmetrical fin guides 6, 6' is manufactured by cutting the fin guides 6 and 6' into pieces from the center between the left and right sides using the front and rear directions as cutting planes (in the direction of the arrows A to A' in FIG. 3). The fin guides 6 and 6' were arranged with the groove 2 sides facing each other, and the fin 7 was spanned between the grooves 2 of each step, and each end of the fin was inserted into the groove to form a height of a predetermined dimension. This is the single-flow louver a shown in FIG. Incidentally, by bonding and pasting the rear surface of one fin guide 6 to the rear surface of the other fin guide 6', a chevron-shaped fin guide 8 for a chevron-shaped louver shown in FIG. 5 can be formed.

(Effects of the Invention) According to the present invention, a fin guide is mass-produced and provided, which facilitates groove machining and can always align fins in parallel without being affected by the machining accuracy of the groove 2 such as the groove pitch. There are features that allow it.
