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 is set slightly larger than the maximum adjustment height ah, as shown in Figure 7. .

Therefore, since the absolute value of the rail height is large,
Firstly, it is difficult to sweep out dirt and other debris from the top surface of the bottom frame.Secondly, the top surface of the bottom frame does not look good and is painful to walk on with bare feet.Thirdly, material consumption is low. Fourthly, since the space between the lower end of the lower stile and the upper surface of the lower stile increases due to height adjustment, even if airtight material is installed, the airtight/watertight performance will not deteriorate significantly when adjusting beyond the elastic range. There were drawbacks such as the inability to

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 stile, but since the amount of material used for the auxiliary stile is large, the value of the sliding door increases, resulting in a negative economy. There were drawbacks such as a complicated holding structure for the lower stile and difficulty in height adjustment.

[Object of the present invention] In view of the above points, the present invention always closes off the space between the lower stile and the lower frame regardless of the height adjustment, and
By attaching a closing member to the lower stile that can slide as the sliding door opens and closes, it maintains airtightness even when the height is adjusted.
To make it possible to lower the rail height without affecting watertight performance at all, thereby making it easier to sweep out dirt, etc., improving the appearance of the upper surface of the lower frame, and saving materials. With the goal.

[Means for achieving the object] In order to achieve the above object, the window sealing device according to the present invention has a length approximately equal to the length of the lower sill of the sliding door, a vertical strip-shaped insertion portion, and an elastic member projecting downward. A shielding member having an airtight material holding part that holds an airtight material and a locking part is held in contact with the outer wall of the sliding door lower stile in the insertion part so as to be able to rise and fall freely, and the lower part is formed in a step shape. A rail having a jaw protruding toward the outdoors is provided at the joint between the horizontal wall and the vertical wall of the frame, and a fitting opening toward the outdoors is provided between the jaw of the rail and the horizontal wall connected to the lower end of the vertical wall. forming a fitting portion, and fitting the locking portion of the shielding member into the fitting portion to lock the jaw of the rail;
The airtight material is elastically pressed against the upper surface of the horizontal wall of the lower frame on the outdoor side of the rail.

[Function] In the above configuration, regardless of the height of the sliding door, the blocking member always comes into contact with the outer wall of the lower stile of the sliding door, and the locking part of the blocking member locks with the jaw of the rail. The airtight material is elastically pressed against the upper surface of the lower frame.

[Embodiment of the present invention] Next, an embodiment of the present invention is illustrated in FIGS. 1 to 4.
This will be explained based on the diagram.

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

Sliding doors D ₁ and D ₂ built in a sliding manner between the upper frame H and the lower frame S have lower frames 1 and 1, respectively.
1', shielding members s ₁ and s ₂ having a length approximately equal to the length of each lower stile are attached so as to be movable up and down.

The attachment state of the inner sliding door's closing member s ₂ to the lower stile 1' and the relationship of the lower frame to the rail 2' are the same as the attachment state of the outer sliding door's shielding member s ₁ to the lower stile 1 and its relationship to the rail 2. Therefore, I will only explain the latter and omit an explanation of the former.

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 indoor end of 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 shielding member s ₁ serves as a sliding door in the insertion portion 3.
It is held in contact with the outer wall 1a of the lower stile ₁ of D1 so as to be able to rise and fall freely. Although the insertion portion may be brought into 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 this case, a gap approximately equal to the wall thickness of the insertion portion should be provided between the outdoor bearing piece of the door chassis 7 attached to the insertion portion 3 at the front and back of the lower stile 1 and the outer wall of the lower stile. , the insertion section 3 can be held in the gap so as to be movable up and down. However, instead of the above-mentioned holding structure, as shown in FIGS. 4 and 5, a convex wall 10 is provided on the inner surface of the back wall 9 of the vertical stile 8 on the left and right sides of the sliding door,
The longitudinal end portion of the insertion portion 3 may be fitted between the convex wall and the inner surface of the outer wall 11 of the vertical stile so as to be able to move up and down.

Both the guidance by the gap between the door carriage base 7 and the lower stile outer wall 1a and the guidance by the gap between the convex wall 10 and the outer wall 11 of the vertical stile may be used together. In any case, due to such a guiding action, the shielding member s ₁
However, it is possible to move up and down smoothly while keeping the insertion part 3 in contact with the inner surface of the outer wall of the lower stile, and the space between the shielding member _s1 and the outer wall of the lower stile 1 is kept airtight and watertight. It will be done.

When installing the sliding door D ₁ equipped with this blocking member s ₁ inside a window frame, after fitting the upper stile 12 to the upper frame H and immediately before positioning the door roller 7a directly above the rail 2, Lower the closing member s ₁ and attach the airtight material 6 to the lower frame S
Press the upper surface of the sliding door, move the lower part of the sliding door slightly toward the indoor direction, place the door roller on the rail 2, and attach the locking part 5 to the jaw 2a formed on the outdoor side part of the rail 2. Slidably contact. Then, when the pressing force is removed from the blocking member _s1 , 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, so that the space between the shielding member and the upper surface of the lower frame is made airtight and watertight. Since the closing member cannot move upward, even if the height of the lower stile 1 from the upper surface of the lower frame changes due to height adjustment of the sliding door, the airtight material 6 remains in the same state and is held in pressure contact with the upper surface of the lower frame. Closing member
The airtightness and watertightness of _s1 and the airtight material 6 remain constant regardless of the height adjustment of the sliding door.

The rail 2 has a jaw 2a that is formed on the upper surface of the joint between the horizontal wall _h1 and the vertical wall p of the lower frame that is formed in a step-like shape and projects toward the outdoors, and that the jaw 2a and the vertical wall Horizontal wall h ₂ connected to the lower end of p
A fitting portion 2b that opens to the outdoors is formed between the two.

The locking portion 5 of the blocking member _s1 is fitted into this fitting portion and locked to the jaw 2a.

In this way, by installing the shielding members s ₁ and s ₂ , the space between the lower stile and the upper surface of the lower frame is always closed, regardless of whether or not the height of the sliding door is adjusted or the amount of adjustment is made, thereby ensuring airtightness.・Since watertightness is ensured, the sliding door rail 2,
2' can be made much lower in height than conventional ones. Therefore, it is possible to easily sweep away dirt and the like existing on the upper surface of the lower frame, the appearance of the upper surface of the lower frame is improved, and walking on the upper surface of the lower frame with bare feet does not cause unbearable pain as in the past. There is no.

In a preferred embodiment, reference numeral 13 denotes a groove provided on the outside of the airtight material holding portion, into which an auxiliary rail 14 protruding from the upper surface of the lower frame is slidably fitted. This groove 13 and the auxiliary rail 1
By fitting 4, the airtightness between the blocking member and the lower frame is further improved, and secondly, in order to remove the sliding door from the window frame, the sliding door can be lifted and the door roller can be removed from the rail 2. When removed, it is possible to prevent the lower end of the shielding member from sliding on the upper surface of the lower frame and falling off from the lower stile, and the sliding door being prevented from accidentally falling down due to the door roller sliding on the upper surface of the lower frame.

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

In the above embodiment, in order to lock the blocking 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 located at a constant position with respect to the bottom frame. However, the door carriage also always remains in the same 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 is installed on the indoor side of the window frame.
_D3 is installed, and one end of the screen door fits into the handle part 15 of the inner sliding door, so that when sliding door _D2 is closed, the screen door is also closed at the same time.

[Effects of the Invention] As described above, according to the present invention, the blocking 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 The locking part is fixed in contact with the jaw of the rail, which is a member that always remains at a fixed position relative to the lower frame, so as to be immovable and slidable in the longitudinal direction of the rail, and is held in the blocking member. Since the airtight material 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 is unstable regardless of the height adjustment of the sliding door.
Maintains high airtightness and watertightness.

Since the locking portion is locked to the jaw directly below the rail, the blocking member can be slid stably, and the locking portion can be formed small and easily.

In addition, the rail has a fitting part that opens outdoors between the jaw and the horizontal wall that connects to the lower end of the vertical wall, and the fitting part receives the locking part, so the height of the rail is lower than before. Therefore, it becomes easy to sweep away dirt and the like from the upper surface of the lower frame, there is no problem in walking around with bare feet, and 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.
