Description

[Detailed description of the invention] This invention has a waterproof and dustproof structure against infiltration of rainwater and dust that occurs in the sliding window section, which is fitted into the window frame and configured to open and close two panes of glass by pulling them sideways against each other. It is related to.

Conventionally, sliding windows used in general residential buildings and various vehicles, especially sliding windows used in bus bodies, etc., are located on the side of the vehicle body, between the window glass and the window frame, and at the sill area, etc. It is constructed so that the window glass can move smoothly, and this also serves to temporarily stop the rainwater that accumulates during rainy days, and also to prevent dust and other particles from entering the room. In addition, in order to prevent rainwater and cleaning water for cleaning the car body from entering the vertical gap between the outer window glass and the inner window glass, a tape-like cloth material, flat woven cloth, synthetic resin molding, etc. Various filling materials have been pasted on the windows to make them dustproof and waterproof, but since the inner and outer glass of these windows moves when the windows are opened and closed, the gaps between them are still incompletely sealed, allowing a large amount of water to seep in during rainy weather. They stay on window sills and move around, sometimes causing damage by wetting passengers' clothes.

However, if we try to improve the waterproof and dustproof functions of the structure by relying on these simple means of interposing fillers, it becomes necessary to make the mutual gaps denser.
If this is made denser, the sliding force required to pull the side window glass horizontally will increase due to the increase in frictional force, and it will become heavier, leading to a basic structural problem in which nimble sliding becomes impossible.

The present invention solves this problem by improving the basic structure, and will be explained below using an example in which the structure is applied to a sliding window of a vehicle such as a bus body.

1 is the window frame of the main opening/closing window, and 2 is the outer window glass that fits into it and slides horizontally.

3 is the same inner window glass that can be opened and closed by sliding each other.

4 is the inner end of this outer window glass 2.

Further, the head portion has an L-shaped portion 5 made of support members bonded to the vertical edges of the portions of the inner ends of the inner window glass 3 that overlap each other when the window is closed, so as to sandwich the glass.

Further, in this example, the L-shaped portion 5 of the support member 4 has cylindrical hollow portions 6, 6' so as to face each other inwardly and abut against each other.
The deformable sealing members 7, 7' having the same shape are supported at their bases by adhering to or sandwiching them into the supporting member 4.

These deformable sealing materials 7, 7' are made of rubber material, synthetic resin material, fiber material, etc., and are deformed by the external pressure applied by the hook when the window is closed, and are designed so that they can restore themselves when no pressure is applied. Hollow or selectively molded into other shapes are used.

8. 8' is arranged so that when the window is closed, the upper and lower ends of the overlapping portion of the outer window glass 2 and the inner window glass 3 straddle the center boundary between the respective sills of the outer window glass and the inner window glass of the window frame 1. , is an opening material that is adhesively fixed to the threshold side using an adhesive using the notch part of the leg α and the adhesive part with the threshold surface, and is made of rubber paper, sponge material, soft synthetic resin material, etc. as described above, and is The top surface is smooth and has an inclined surface .beta., which allows the window to be mounted so that the surfaces are facing each other vertically so that excess rainwater and washing water can flow down outside the window.

In addition, if necessary, the opening materials 8, 8' may be used in plural numbers on the surface, especially in the contact area with the moving inner and outer window glass surfaces, especially in cases where the contact gap between the moving inner and outer window glass surfaces changes greatly. An external shape with a striped fin piece 9.10 is used.

Due to the combination structure as described above, when the present invention is used, when the inner and outer window glasses are closed in rainy weather, the opposing L-shaped portions pressurize the respective moldable sealing materials mutually and deform them in the perpendicular direction, thereby deforming the respective moldable sealing materials. Since the overlapping part adheres to each opposing glass surface, this part can perform its waterproof function, but in addition, the upper and lower opening materials adhere and fix to the window sill,
This functions to prevent water from leaking into the room from the sill of the window frame.

In other words, rainwater and washing water that descends through the upper opening material travels through the sealing material and reaches the lower opening material, and then flows along the slope β and is discharged toward the remaining sill of the outer window glass. Water from entering the room is completely prevented.

In addition, since the opening material that is fixed to the water honey by means such as adhesive does not structurally have the function of deforming itself and preventing rainwater from entering like the sealing material, a fin piece was attached to the surface of this material. Using a waterproof material reduces the contact resistance with the window glass surface and increases the waterproofing effect.

Therefore, when used in a sliding window with a large gap and a large sliding length, the effect can be further enhanced.

In this way, when the window is slid open, the abutting pressure between the opposing shaped parts is released, so the deformable sealing material is restored to its shape and no contact pressure is applied to the inner and outer glass surfaces, which improves its sliding function. Not only does it have the extremely excellent effect of being able to be opened and closed easily without interfering with the interior of the vehicle, but it also has the advantage of being able to be easily opened and closed without interfering with the interior of the vehicle. Similarly, when the door is closed, extremely effective dustproofing effects can be achieved.

In addition, when this structure is used for window structures in general buildings, especially windows with a sash structure, even extremely large sliding windows have sills, rails, etc. at the bottom, making them completely dust-proof like never before. This is a completely new invention that can demonstrate its waterproofing effect without causing any damage, and is highly effective when applied to various types of sliding windows.
