Description

[Detailed description of the invention] [Industrial field of application] This invention relates to an airtight structure that also serves as a door stop for a satsui window.

[Conventional technology]

In general, a sash window, for example a sliding sash window that is made of a set of two shoji that can be opened and closed, has a set of vertical frames 2, 2 and upper and lower frames 3, 4, as shown in FIG. It is composed of a window frame 1 consisting of a window frame 1, and a pair of shoji 5 consisting of a pair of central and frame side vertical frames 6, 7 and upper and lower frames 8, 9. Each shoji 5 fitted in 1 so as to be openable and closable,
5 is provided with various regulating members, reinforcing members, air-tight members, etc. suitable for each purpose in order to smoothly open/close and maintain airtightness in the closed state.

In such a sash window, the vertical frame 2 of the window frame 1
There is an airtight structure that also serves as a doorstop between the frame-side vertical stile 7 of the shoji 5 that is opened/closed and moved in and out of the shoji 5.
This airtight structure is shown enlarged in FIGS. 2a and 2b.

That is, in the case of an airtight structure that also serves as a door stop for a conventional sash window, for example, a protruding piece having a fitting groove 10 is provided protruding from the vertical frame 2 over the entire length in the vertical direction inside, and the fitting groove An airtight member 12 which is also used as a door stop and is fitted in the door stopper 10 maintains airtightness between the door stopper and the protruding piece 11 which is protruded from the frame side vertical stile 7. The airtight member 12 has a main body 13 made of a relatively hard synthetic resin and has a convex cross section. A linear fin portion 15 that protrudes somewhat long, and a bent fin portion 16 that protrudes so that a portion thereof is bent at the other side.
It has a shape in which these are integrated with a relatively hard synthetic resin and is continuously molded in the longitudinal direction.

[Problem that the invention attempts to solve]

In the airtight structure of the conventional sash window that also serves as a doorstop configured as described above, when the shoji 5 is closed, the flat end surface 14 of the main body 13 of the airtight member 12 that also serves as a doorstop and the protrusion of the shoji 5 When the distance from the piece 11 is large, the length of the fins 15 and 16 is long;
In such a case, the frictional resistance between the fins 15 and 16 and the protruding piece 11 becomes large, making it difficult to open and close the shoji 5.
If the distance between the fins 15 and 16 is small, the length of the fins 15 and 16 will be short, making it easier to open and close the shoji 5, but gaps will be created between the fins 15 and 16 and the protruding piece 11, and the airtightness will deteriorate. There was a problem that it became difficult to secure. During rainstorms, a large amount of pressure is applied to the shoji 5.
As a result, as shown in FIG. 2b, the protruding pieces 11 of the shoji 5 and the protruding pieces of the vertical frame 2 equipped with the airtight member 12 tend to collide with each other, as shown in FIG. 2b. Each of the fins 15 and 16 is compressed and flattened, and the protruding piece 11 of the shoji 5 is pressed against the airtight member 1.
violently collided with the distal end surface 14 of the main body 13 of No. 2,
Due to the influence of the door stop member (not shown) on the vertical frame 2 side, there is a risk that a concentrated load will be applied to the protruding piece 11 of this shoji 5 and it will deform. In addition to causing vibration noise depending on the condition, there was also the problem that the elastic restoring force could not follow the vibration, resulting in a loss of airtightness, allowing drafts to enter and generating wind noise. .

This idea solves the problems mentioned above,
Although the shoji can be opened and closed relatively easily, the fins can be brought into reliable contact with the protruding piece on the other side, and even when a large force is applied to the shoji, such as during a storm, the shoji can be easily opened and closed. The object of the present invention is to provide an airtight structure which also serves as a door stop for a sash window, which can suppress deformation of the window and which also has good airtightness.

[Means for solving problems]

The airtight structure that doubles as a door stop for a satsui window according to this invention has a main body made of synthetic resin, a locking part is formed at the base end of the main body, and a locking part is formed on one side of the tip of the main body. At the same time, a long fin part that is partially bent and protrudes from the other side of the tip which is stepped and recessed with respect to the protrusion part is formed, and a straight short fin part that protrudes obliquely from the tip of the protrusion part. The fins are each integrally formed from a soft synthetic resin, and the fins are formed continuously in the longitudinal direction to form an airtight member that also serves as a door stop, and the locking portion of this airtight member is provided in the vertical frame of the window frame. Fitting and locking at least one of the protruding piece and a protruding piece provided on the vertical frame of the shoji fitted in the window frame, and the tips of the long and short fins of the airtight member,
It is made to abut on the other of the two protruding pieces.

[Effect]

The airtight structure of this invention, which also serves as a door stop, has a protrusion on one side of the main body of the airtight member, a short soft fin on the protrusion, and a long soft fin on the other side of the main body. Since the fins are formed, the distance between the protruding piece fitted with the airtight member and both fins is small on one side of the main body and large on the other side. By bringing the long and short fins into contact with the protruding pieces on the other side, the shoji can be opened and closed relatively easily.
The distance between the main body and the protruding piece on the other side is narrow on one side of the main body and wider on the other side, making it difficult to create a gap between the long fin and the protruding piece on the other side, ensuring good airtightness. can. In addition, when large pressure is applied to the shoji during a storm, etc., the vertical stile of the shoji can be supported by the vertical frame of the window frame via the protrusion, which prevents the shoji from deforming into an arched vertical section. It is possible.

〔Example〕

Hereinafter, one embodiment of this invention will be described in detail with reference to FIGS. 3 to 5.

FIG. 3 shows a cross section of an airtight member that also serves as a door stop according to one embodiment, and FIGS. are shown respectively.

In FIG. 3, the airtight member 20 that also serves as a door stop is
Similar to the conventional example, it has a main body part 21 made of relatively hard synthetic resin, and a frame side vertical wall of the shoji 5, which is one of the window constituent members, is provided at the base end of the main body part 21. A locking part 22 is fitted and locked in the fitting groove 17 of a protrusion piece 11 that protrudes from the frame 7 over the entire length in the vertical direction.
3 are formed respectively, and this protrusion 2
On the other side of the tip which is recessed by giving a step to 3, there is a long fin part 24 that protrudes so as to partially bend.
The short linear fins 25 projecting diagonally at the tips of the protrusions 23 are integrally formed from a relatively soft synthetic resin, and these are continuously molded in the longitudinal direction. ing.

As shown in FIGS. 4 and 5, when the locking portion 22 of the airtight member 20 is fitted and locked in the fitting groove 17 provided in the protruding piece 11 of the vertical stile 7 of the shoji 5, the window The short fins 25 provided on the protrusion 23 and the main body without the protrusion 23 are attached to the airtight seal surface 19 of one of the protrusion pieces 18 that protrudes from the vertical frame 2 of the frame 1 over the entire length in the vertical direction. The long fin part 24 provided at the tip of the part 21 is pressed against the shoji 5 with a required elastic force when the shoji 5 is closed.

Further, the locking portion 22 of the airtight member 20 having a cross-sectional shape substantially similar to that shown in FIG. The fin portion 25 and the long fin portion 24 are pressed against the side surface of the projecting piece 11 of the vertical frame 7 opposite to the surface where the fitting groove 17 is provided.

In the airtight structure according to this embodiment, the short fins 25 and long fins 24 of the airtight member 20 shown in FIG. 3 are pressed against the sealing surface 19 of one of the mating protruding pieces 18. Then, the short fins 25 maintain the airtightness of the small gap between the airtight sealing surface 19 and the protrusion 23 under normal conditions, and when wind pressure is applied, the airtight sealing surface 19 and the protrusion 23 come into contact with each other. When trying to do so, it acts as a buffer between them. Furthermore, even if wind pressure of both positive pressure and negative pressure is applied to the shoji 5, the airtight sealing surface 19 can be
Since there is only a small gap between the shoji 5 and the short fins 25, the vibration of the shoji 5 is restrained and regulated via the short fins 25. This eliminates the concentrated load caused by the vibration inertia, and also prevents the positive and negative wind pressure. At the level of pulsation, the noise can be reduced in conjunction with the fact that the protrusion 23 is made of hard synthetic resin. In addition, since the long fins 24 are formed on the distal end surface of the main body 21 which is stepped and recessed from the protrusion 23, the airtight sealing surface 19 and the protrusion 23 may come very close to each other even during a rainstorm. Even in such a case, the long fins 24 will not be bent, and the sealing action on the airtight sealing surface 19, that is, the airtightness, will always be ensured, and the intrusion of drafts etc. can be prevented. Furthermore, a similar effect occurs on vertical frame 2.
This can also be achieved by the airtight member 20 attached to the protruding piece 26 of.

Although the airtight structure of this embodiment is applied to the double sliding window shown in FIG. 1, this invention can also be applied to a single sliding window. Further, in the embodiment, two protruding pieces 18, 2 are provided on the vertical frame 2 of the window frame.
6, the protruding piece 11 of the vertical stile 5 of the shoji was provided, and the airtight members 20, 20 were attached to the protruding pieces 11, 26, respectively. The airtight member may be attached to the provided protruding piece, and when the shoji is closed, the short and long fins provided on the airtight member may be brought into pressure contact with the protruding piece provided on the other side of the vertical frame or the vertical stile. However, if two airtight members are provided as in the above embodiment, these effects can be increased synergistically.

[Effect of idea]

As detailed above, when using this idea,
A protrusion is provided on one side of the main body of the airtight member, a short soft fin is formed on the protrusion, and a long soft fin is formed on the other side of the main body, so that the airtight member can be attached. The distance between the protruding piece and both fins is small on one side of the main body and large on the other side. By bringing the long and short fins into contact with the protruding pieces on the other side, the shoji can be opened and closed relatively easily, but the distance between the main body and the protruding pieces on the other side is narrow on one side of the main body. It is wider on the other side, making it difficult to create a gap between the long fin and the protruding piece on the other side, ensuring good airtightness, and also when large pressure is applied to the shoji during storms, etc. By being able to support the vertical stile of the shoji on the vertical frame of the window frame via the protrusion, it is possible to suppress deformation of the shoji into an arched vertical section, and the airtightness is good even when a large force is applied. There is an effect.
