Description

[Detailed Description of the Invention] The present invention relates to a ventilation frame provided in an aluminum sash sliding door.

Recently, aluminum sashes have become widely used in offices and homes.

Most of the sliding doors used for this purpose have a glass plate fitted into an aluminum frame, and the airtightness between the sliding doors and between the sliding door and the sash frame is very good.

Therefore, ventilation must be taken into consideration for rooms equipped with aluminum sashes.

For this reason, a ventilation means was installed in a part of the sliding door.

As this type of ventilation means, there is one in which a ventilation frame is provided in a part of the glass door, for example, in the upper part.

Conventionally, this type of ventilation frame has a small sliding door with a hole that slides over a small area in a part of the door in the unrivaled window hole, and a hole that matches the hole in the small sliding door is provided in the door so that the small sliding door can be moved. There were various structures available, such as aligning the two holes to allow ventilation, or blocking the holes by alternating them, but all of them had complex structures and were not easy to manufacture. However, the performance was not sufficient.

The ventilation frame of the present invention was developed to eliminate the drawbacks of the conventional ones, and its gist is as described in the above-mentioned utility model registration request.One embodiment will be described below with reference to the drawings.

In the ventilation frame body 7, holes 4 of the same shape and the same pitch are arranged horizontally, and the upper part becomes a widening part 5 that expands outward to about the thickness of the glass plate so that the upper frame is fixed to the upper frame 2. and the lower part becomes a widening part 6 corresponding to the widening part,
Underneath it is integrally formed a middle frame 3 which is open downward and has a U-shaped cross section.

The shutter 9 is provided with a louver 8 facing outward.

The movable plate 12 has holes 10 which are provided in approximately the same shape and dimensions as the holes 4 and at the same pitch, and the holes 10 are provided in the enlarged portion 5 of the main body 7.
, 6, and can slide on the rail 11 protruding toward the shutter.

The shutter 9 has both upper and lower edges 13, 14 bent into a crank shape, and grooves 15.1 facing inward in the upper and lower widening portions 5, 6.
It is inserted into 6.

In the drawing, 17 is a rail that suppresses the upper bent part of the movable plate to prevent the movable plate 12 from moving upward during operation.
It protrudes from the main body 7 as shown in FIG.

Reference numeral 18 denotes a movable plate moving knob attached to the movable plate 12 and provided inside the main body 7.

The movable plate 12 and the knob 18 are coupled to each other by passing a locking portion 18a, which is integrally formed on the side surface of the knob 18 and having a substantially oval cross section, through a long hole 20 drilled below the main body 7 to the outside of the main body 7. (on the right side in FIG. 1), and the lower end of the movable plate is bent slightly to form a notch 12a, and the movable plate 12 is formed on the upper surface of the locking part 18a in the notch 12a. This is done by engaging the groove 18b.

Since the movable plate 12 and the knob 18 are connected in this way, when the knob 18 is moved indoors (left side in FIG. 1), the movable plate 12 moves left and right accordingly.

Further, a groove 18C is formed in the lower base of the locking portion 18H, and when the knob 18 is assembled into the elongated hole 20, the groove 18C
Since C engages with the edge of the elongated hole 20, the knob will not come off and fall indoors.

The main body 7, movable plate 12, and shutter 9 can be made of any material, but if the main body is made by extrusion molding of aluminum alloy, the shutter 9 can be inserted into the groove 15, 16 and the hole 4 and the louver 8 can be aligned in phase. This is convenient for fixing the upper edge 13 in the groove 15 by slightly crushing the expanded portion 5 with a press or the like.

Since the present invention is constructed as described above, the knob 18 is placed on one side,
If the holes 4 are moved by at least one pitch, the holes 4 in the main body 7 and the holes 10 in the movable plate 12 will match.

Ventilation is thus performed through the louvers 8, holes 10, and holes 4.

In this case, since the movable plate 12 rests on the rail 11 on the inside, there is little chance of dust accumulating between the rail and the movable plate 12, and even if dust does accumulate, it will fall off the rail due to the movement of the movable plate and the movable plate will not slide. movement is unimpeded.

With the above configuration, the main body 7, the movable plate 12, and the shutter 9 can be easily made without any overhanging parts, except for the protruding part of the louver and the knob, so this assembly can be made easily with respect to the middle stile. made symmetrically.

Therefore, when attaching the middle stile 3 to the left and right stile, the bifurcated leg 3a
, 3b by the width l (Figs. 6-7) where the thin part of the ventilation frame (part A in Fig. 1) is inserted into the groove 19 (Fig. 7) of the left and right stiles as shown in Fig. 8. By cutting it out, it can be attached to an existing glass door without losing its aesthetic sense, so it has a great practical effect as a ventilation frame that is compatible with all types of sliding doors.
