Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a blade attachment structure for a louver door (including a louver door that also functions as a screen door).

(Prior art) It is well known that so-called glazing doors have been widely used in the windows and entrance doors of ordinary houses, as they have ventilation and light-blocking properties, and can also protect privacy (blinding). As such, various types of louvers have been developed and put into practical use, ranging from those with fixed louvers to those with movable louvers.

(Problems to be solved by the invention) However, each of the conventional louver doors described above has the following drawbacks. First of all, in the case of fixed-type louvers, each louver is generally fixed at the same angle so that the entire door performs the above function. The problem is that even if there is a request that it would be better to have transparency or translucency rather than concealment at the top (above the position) or below (also near the feet), it is not possible to meet that request. There is a point. Furthermore, when applied to the windows of high-rise residential buildings, the angles required for blindfolding differ between the upper and lower floors, so even in this case, sufficient measures cannot be taken for each. On the other hand, a movable louver door has the convenience of allowing the user to adjust the angle of the louver as appropriate, but it is necessary to incorporate a new means into the door frame to adjust the angle of the louver. , the structure becomes more complex and the product cost increases accordingly. Moreover, since the blade angle of the entire door can generally be changed all at once, it is impossible to require different functions for different parts of the door as described above. It is necessary to provide movable means for each part, which makes the structure increasingly complex, increases product cost, and reduces versatility.

The present invention was developed in view of the above circumstances, and is a new and simple structure that allows the user to change the blade angle appropriately during the turning stage or according to the location conditions or the user's preference. It is an object of the present invention to provide a structure for attaching a wing to a louver door.

(Means for Solving the Problems) The configuration of the present invention for achieving the above object will be explained based on the attached embodiment drawings. Figure 1 is a partially cutaway perspective view of an entrance door adopting the structure of the present invention, Figure 2 is an enlarged exploded perspective view of the line in Figure 1, and Figures 3 and 4 are fixing members adopted in the present invention. FIGS. 5 and 6 are partially cutaway perspective views showing other embodiments of the mounting structure of the present invention. That is,
The present invention is a blade mounting structure for a louver door A, which is framed by vertical and horizontal beams 1 and 2, and a large number of louver blades 3 are installed between the vertical beams 1 and 1. , 1, a plurality of blade fixing members 4... in which a plurality of blade end fitting grooves 41... having at least two types of angles are regularly spaced are arranged on the vertical beams 1, 1.
1, and by fitting and fixing the ends of the louver blades 3 into the fitting grooves 41, the louver blades 3...
The gist of this invention is a structure for attaching a wing to a glazing door, which is characterized in that it can be attached selectively at an angle of .

In the figure, the vertical and horizontal bars 1 and 2 are both made of extruded materials such as aluminum, and the opposing inner surface of the vertical bar 1 has a receiving portion into which the blade fixing member 4 can be fitted linearly along the longitudinal direction. 11 is formed, and the blade fixing member 4 is obtained by injection molding of hard synthetic resin. The blade fixing member 4 is a belt-shaped plate of a fixed length, and on one side thereof, blade end fitting grooves 41 having at least two types of angles are regularly spaced apart.

(Function) In order to assemble the louver door A using each member of the above configuration, the lower horizontal bar 21 and the vertical bars 1, 1 on both sides are fastened together with fasteners, and then a plurality of louver blades 3... The plurality of shutter blades 3... and the blade fixing members 4, 4 at both ends are selectively fitted into blade end fitting grooves 41 of a desired angle recessed in the blade fixing member 4. Thus, a louver door unit body A ₁ is formed, and the blade fixing member 4 of this unit body A ₁ is fitted into the receiving portion 11 of each of the vertical bars 1, so that each louver blade 3 is substantially fixed to the vertical bar 1, The area between the vertical bars 1 and 1 is filled with the above-mentioned unit body A ₁ by repeating this operation one after another, interposing the middle bar 21, etc., and finally, the upper horizontal bar 2 is stopped. Once it is attached and fixed, the louver door A as shown in Figure 1 will be completed. At this time, since the blade fixing member 4 is recessed with blade end fitting grooves 41 having at least two types of angles, by selecting the fitting grooves 41 as appropriate, the louver door A can be fixed. The angle of the louver blades 3 can be changed for each part. Therefore, when applying the entrance door as shown in the figure to a condominium, etc., the angle of inclination of the louver blades 3 should be increased in positions where the line of sight of people walking on the external passageway is likely to be seen, and in other areas It is possible to devise measures such as making the inclination angle horizontal or gentle to ensure visibility or translucency from inside the room. In addition, even when using a glazing door that doubles as a screen door for the window on the balcony side of a high-rise residential building, the viewing angle from the outside differs depending on the floor, so this should be taken into consideration during the construction stage and the angle of each glazing blade 3 should be adjusted to fit the above-mentioned grooves. 41... can be adjusted for each floor.

(Example) The present invention will be explained in more detail below with reference to Examples.

(Example 1) In Fig. 2, the blade end insertion groove 41 is composed of two types of grooves: a substantially horizontal groove 411 and a steeply sloped (approximately 45°) groove 412. This shows that the blades are formed in pairs and are recessed at equal intervals along the longitudinal direction of the blade fixing member 4 in an intersecting state. These grooves 411..., 412... are formed in the shape of cuts from one side of the blade fixing member 4. On the other hand, in the blade fixing member 4 shown in FIG. 3, the two types of grooves 411..., 412... are still in an intersecting shape, but one side of the fixing member 4 is completely drilled. Indicates that it was formed in Furthermore, the blade fixing member 4 in FIG. 4 has two types of grooves 41 similar to those described above.
1..., 412... are formed alternately without intersecting each other, and any of these are preferably adopted, but they are not limited to the example shown, and the blades should be inserted as much as possible in the molding. It is obvious that the selection range of the inclination angle of the louver blades 3 can be further expanded if the grooves 41 are formed at three or more angles in an intersecting manner or alternately.

(Example 2) FIG. 2, FIG. 5, and FIG. 6 show differences in the means for fitting the blade fixing member 4 to the vertical beam 1, which will be explained in more detail. In the case of FIG. 2, a groove-shaped receiving part 11 with a narrow opening is formed at the same time as extrusion molding of the vertical bar 1, and the receiving part 11
In the case of FIGS. 5 and 6, the blade fixing member 4 is inserted from the vertical direction.
The receiving part 11 is formed in a stepped shape and a hook-shaped holding member is fixed to the vertical frame 1 via screws 121 (this may be done by other snap-in type means), thereby attaching the blade to the vertical frame 1. Further, in the case of FIG. 6, where the fixing member 4 is integrated, a dovetail groove 42 is formed along the longitudinal direction on the opposite surface of the blade fixing member 4 where the groove 41 is formed. A protrusion 111 having the same cross section as the dovetail groove 42 is protruded on the bottom surface of the receiving part 11 along the longitudinal direction, and by fitting the dovetail groove 42 and the protrusion 111 along the longitudinal direction. , blade fixing member 4 and vertical beam 1
It is designed so that it can be integrated with the In the case of the fitting means shown in FIGS. 5 and 6, once the blade fixing member 4 in which the blade end insertion groove 41 is formed in the shape of a notch from one side as shown in FIG. Even if the door has a built-in louver blade 3, by removing the presser member 12, the louver blade 3 can be pulled out along the groove 41.
Even after construction, the angle can be changed arbitrarily and the blades 3 can be cleaned in a general household. In particular, in the case of FIG. 6, even if the holding member 12 is removed, the blade fixing member 4 is still integrated with the vertical beam 1 by fitting the dovetail groove 42 and the projection 111, so that the unit body A ₁ is The blades 3 can be safely attached and detached or cleaned without falling down.

It goes without saying that the present invention is not limited to the above embodiments, and that other changes can be made without departing from the scope of the present invention.

(Effects of the invention) As mentioned above, the louver door blade mounting structure of the present invention allows the angle of the louver blade to be easily changed during or after construction, and the conventional function of ventilation is improved. The security, light shielding, and privacy protection can be adjusted appropriately according to the location conditions and the user's preferences, and the structure is extremely simple, so it can be supplied at a price that is not much different from conventional fixed glazing doors. It has practical benefits such as high versatility because it can also be used for various purposes, and its value is extremely high.
