Description

[Detailed Description of the Invention] [Technical Field to which the Invention Pertains] This invention relates to a sealing device for a window in which a sliding door is installed, particularly in a window equipped with a sliding door height adjustment mechanism. This invention relates to a sealing device that maintains constant airtightness and watertightness between a frame and a lower stile.

[Prior Art and Its Disadvantages] Generally, when the height of a sliding door is adjusted, the height of the lower end of the lower frame from the upper surface of the lower frame changes. Accordingly, in order to prevent large fluctuations in airtightness and watertightness, conventionally the height rh of the rail r provided on the lower frame S was set slightly larger than the maximum adjustment height ah, as shown in Figure 7. It is set.

Therefore, since the absolute value of the rail height is large, firstly,
It is difficult to sweep out dirt etc. from the top surface of the bottom frame, and secondly,
The appearance of the upper surface of the lower frame is not good and it is rare when walking on the upper surface with bare feet.Thirdly, the material cost is high.Fourthly,
When adjusting the height, the distance between the lower edge of the lower stile and the upper surface of the lower stile becomes large, so even if airtight material is installed, airtightness and watertightness will inevitably deteriorate significantly when adjusting beyond the elastic range.
There were drawbacks such as.

Additionally, an auxiliary stile equipped with a door wheel is fitted inside the lower stile so that it can be raised and lowered, so that the lower end of the auxiliary stile is always positioned close to the top surface of the lower frame, regardless of the height adjustment of the sliding door. It is known that the airtightness is maintained constant by maintaining the auxiliary frame, but since the amount of material used for the auxiliary frame is large, the l11j rating of the sliding door is high, making it uneconomical. The structure for holding the lower stile is complicated, and the height adjustment work is difficult.

[Object of the present invention] In view of the above points, the present invention has the following features, regardless of height adjustment:
By always keeping the space between the lower stile and the lower frame open, and by attaching a shielding member that can slide as the sliding door opens and closes to the bottom (■), the view and watertight performance will not be affected at all by adjusting the height. Moreover, the purpose is to make it possible to reduce the height of the rail, thereby making it easier to sweep out dirt, etc., improving the appearance of the upper surface of the lower frame, and saving materials.

[Embodiment of the Invention] Next, an embodiment of the invention will be described with reference to FIGS. 1 to 4.

Although the illustrated embodiment is applied to double-sliding windows, the present invention can be similarly applied to single-sliding windows.

For the sliding doors Dr and Dz built in a sliding manner between the upper frame 1 (and the lower frame S), each lower stile 1.1' is provided with a shield having a length approximately equal to the length of each lower stile. Member Sm,'
s2 is attached so that it can be raised and lowered.

The attachment state of the inner sliding door's closing member Sz to the lower stile 1' and the relationship of the lower frame to the rail 2' are the same as that of the outer sliding door's closing member Sz.
1 to the lower stile 1 and the relationship to the rail 2, only the latter will be explained, and the former will be explained more carefully.

As shown in FIG. 3, the shielding member S1 includes a vertical strip-shaped insertion section 3, an airtight material holding section 4 provided at the lower end of the insertion section, and an interior curved end at the lower end of the insertion section. An elastic airtight material 6 is made to protrude downward from the airtight material holding part 4 and is held by a method such as fitting.

This blocking member S1 is held in contact with the outer wall 1a of the lower stile 1 of the sliding door D in the insertion portion 3 so as to be freely slidable. Although the insertion portion may be in contact with the outer surface of the outer wall 1a, in order to avoid deterioration of the appearance, it is preferable to hold the insertion portion in contact with the inner surface of the outer wall as shown in the drawing. In that case, the insertion part 3 should be spaced between the outdoor side bearing piece of the door carriage 7 attached at the front and rear of the lower stile 1 and the outer wall of the lower stile, with a gap approximately equal to the wall thickness of the insertion part (J). It is also possible to hold the insertion part 3 in the gap so that it can rise and fall freely. However, instead of the above-mentioned M4 holding structure, as shown in FIG. A convex wall 10 may be provided on the inner surface of the insertion portion 9, and the longitudinal end portion of the insertion portion 3 may be fitted between the convex wall and the inner surface of the vertical (σ) outer wall 11 so as to be able to move up and down.

Guidance by the gap between the door carriage stand 7 and the lower stile outer wall 1a,
Both the guidance by the gap between the convex wall 10 and the outer wall 11 of the stile may be used together. In any case, due to such a guiding action, the shielding member S1 can be smoothly raised and lowered while keeping its insertion portion 3 in contact with the inner surface of the outer wall of the lower stile, and the shielding member S1 and The space between the lower stile 1 and the outer wall is kept airtight and watertight.

When installing the sliding door Di equipped with this blocking member St in the window frame, after fitting the upper stile 12 to the upper frame 1, and immediately before moving the door roller 7a to the true position 1δ of the rail 2, Lower the blocking member S, press the airtight material 6 against the upper surface of the lower frame S, and then move the lower part of the sliding door slightly toward the interior of the room to place the door ii on the rail 2, and The locking portion 5 is slidably brought into contact with a jaw 2a formed on the outdoor side portion of the rail 2. Then, when the push-down blade is removed from the locking member Sl, the locking portion 5 is locked to the jaw 2a of the rail due to the elastic return force of the airtight member 6.

In this way, by locking the locking portion 5 to the rail 2, the pressure contact state of the airtight member 6 to the upper surface of the lower frame is maintained.
The connection member and the upper surface of the lower frame are made airtight and watertight, and
Since the related members cannot be moved upward, even if the height from the top of the bottom frame 1 changes by adjusting the height of the sliding door, the airtight material 6 remains in the same state and is held in pressure contact with the top of the bottom frame. The airtightness and watertightness of the connecting member S1 and the airtight material 6 remain constant regardless of the height adjustment of the sliding door.

In this way, by installing the related members Si and Sz, the gap between the lower stile and the upper surface of the lower frame is always kept open, regardless of whether or not the height of the sliding door is adjusted or the amount of adjustment is made, thereby improving airtightness and watertightness. Therefore, the height of both sliding door rails 2.2- can be made much lower than before. Therefore, it is possible to easily remove dirt and the like existing on the upper surface of the lower frame, and the appearance of the upper surface of the lower frame is improved.1. Therefore, even if you step on the top surface of the lower frame with bare feet, you will not experience unbearable pain like in the past.

Reference numeral 13 denotes a groove provided on the outside of the airtight material holding portion in a preferred embodiment, into which an auxiliary rail 14 protruding from the upper surface of the lower frame is fitted in a freely movable manner. By fitting the auxiliary rail 14 with the auxiliary rail 13, firstly, the airtightness between the related member and the lower frame is further improved, and secondly, the sliding door can be lifted up to remove it from the window frame. This prevents the lower end of the related member from sliding on the upper surface of the lower frame and falling off the lower stile when the door roller is removed from the rail 2, and prevents the door roller from sliding on the upper surface of the lower frame and causing the sliding door to fall down unexpectedly. can.

In addition, by fitting the auxiliary rail 14 into this groove 13, the related member maintains a constant height with respect to the lower frame.
The airtight material 6 does not come into pressure contact with the horizontal upper surface of the lower frame, and is attached to the rail 2.
It is sufficient to maintain airtightness by press-contacting the outdoor side vertical surface of 2'.

In the above embodiment, in order to lock the evacuation member at the same height regardless of the height of the sliding door, the locking part 5 is locked to the jaw of the rail that is always at a constant position with respect to the lower frame. However, the door carriage also always remains in a fixed position. Therefore, the same effect can be achieved by locking the locking portion to the lower side of the bearing of the door chassis.

In the illustrated example, a screen door R) 3 is installed on the indoor side of the window frame, and when the handle of the inner sliding door fits into the part 1 of the shutter, the sliding door D2 is closed. The screen door is also closed at the same time.

[Effects of the Invention] As shown in (a) above, according to this invention, the connecting member attached to the lower stile is held movable up and down with the insertion portion always in contact with the outer wall of the lower stile, and , a part in which the locking part always remains at a fixed position with respect to the lower frame, for example, a part in which the locking part is in contact with the jaw of the rail so that it cannot move upwardly but can move freely in the longitudinal direction of the rail, or is locked in the door frame. Since the airtight material held by the related member is pressed against the upper surface of the lower frame, the state of pressure contact of the airtight material against the upper surface of the lower frame remains constant regardless of the height adjustment of the sliding door, resulting in high airtightness and watertightness. Maintain performance. In addition, since there is no need to set the rail height in consideration of the height adjustment valve of the sliding door as in the past, it is possible to make the rail height much lower than in the past, making it easier to sweep away debris from the top of the bottom frame. It is easy to walk, and there is no problem in walking barefoot.
Furthermore, the appearance of the upper surface of the lower frame is improved. In addition, the amount of material consumed for the bottom frame can be reduced.
