Abstract

PROBLEM TO BE SOLVED: To dispence with use of a knife-like tool in replacement work of a window glass to safely facilitate work by using a tool such as cutting pliers. SOLUTION: In this device, a wire 5 is arranged in a sealing material 4 filled between a window glass 1 and a frame 3 for the window glass 1 along frame 1. One end of the wire 5 is somewhat protruded from the sealing material 4 at a preset position. The other end of the wire 5 is located near it. When the window glass 1 is replaced, one end of the wire 5 is gripped and pulled with cutting pliers to cut the sealing material 4. The need to cut the sealing material 4 with a knife is therefore eliminated, resulting in safe and easy work.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window glass fixing device, and more particularly to a window glass fixing device suitable for a vehicle side window.

[0002]

2. Description of the Related Art In railway vehicles, especially express trains,
The side window glass is not openable and closable because of complete cooling and heating. In most cases, the joint with the vehicle outer panel is made water-tight with a sealing material (Japanese Patent Laid-Open No. 05-29131).
No. 2). The tendency has been increasing in recent years for commuter trains and the like.

In such a situation, when the window glass is broken due to a flying stone or the like, replacement of the window glass is performed by cutting a seal material between the vehicle outer plate and the outside of the vehicle using a thin-blade knife to remove the sealing material. It is the actual situation that the replacement work is performed by opening the door and removing the mounting metal fixing the side window glass from the inside of the vehicle.

[0004] Since the sealing material between the side window glass and the vehicle outer panel keeps a water-tight structure and is not usually considered to be removed, a very hard sealing material is used, and the sealing material is cut open. The knives used in such a case necessarily require thin blades. Therefore, during the operation, a considerable force is applied to the thin blade, which is disadvantageous in terms of strength, and the breakage of the knife and the removal of the knife from the sealing material may damage the operator's body, particularly the hand, in the direction of the knife edge. was there.

[0005]

The prior art involves the risk of breaking the knife body or damaging the worker's body when the cutting edge comes off from the sealing material, and the hardness, cutting depth, and the like of the sealing material. Or, in view of the work efficiency, there was no other way but to use a knife with a thin blade.

An object of the present invention is to make it possible to easily replace a window glass.

[0007]

An object of the present invention is to provide a window glass fixing device in which a sealing material is filled between a window glass and a frame to which the window glass is mounted along the entire circumference of the frame. Along with a wire in the sealing material.

According to this configuration, when replacing the window glass, if one end of the wire is gripped and pulled with a tool such as pliers or pliers, the same state as when the sealing material is cut with a knife is obtained. For this reason, the replacement work of the window glass can be easily performed.

When performing glass replacement due to breakage,
To ensure a watertight structure, a certain area of the sealing material filled between the side structure and the side window glass was forcibly dug, buried in the sealing material, and adhesively fixed to the glass surface By pulling one end of a very thin wire, it becomes possible to cut off the adhesive bond between the glass surface and the side structure by the sealing material. on the other hand,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 denotes a side window glass, which shows a laminated glass commonly used in high-speed vehicles. A metal frame 2 molded with packing or a flexible sealing material is attached around the side window glass to facilitate attachment to the vehicle body and to prevent breakage of the glass due to the holding force at the time of attachment. This constitutes a side window glass unit. This side window glass unit is fixed to the side structure 3 by a holding metal 6 from the inside of the vehicle. Although the mounting strength of the side window glass 1 is determined by the holding metal 6, the gap between the side structure 3 and the surface of the glass 1 is filled with a sealing material 4 over the entire circumference to prevent rainwater. A thin wire 5 is arranged inside the sealing material 4 and along the entire outer surface of the glass 1. One end of the wire 5 slightly protrudes from the build-up of the sealing material 4 at a predetermined position. The other end of the wire 5 is located inside the sealing material 4 near the one end.

The wire 5 is filled with the sealing material 4 while being fixed to the surface of the glass 1 with an adhesive. The wire 5 may be located on the outer surface side of the packing 2a. The predetermined position where the one end of the wire 5 is located is a maker name of the glass 1,
It is assumed that the mark of the maker's mark, symbol, etc. is near the printed notation. According to this, the position is obvious at a glance. Or
It is a predetermined corner of a rectangular window.

The replacement operation of the window glass will be described. Since the wire 5 slightly protrudes to a predetermined position, the wire 5 is grasped with general pliers or pliers and pulled. The direction in which the wire 5 is pulled is not the axial direction of the wire 5 but the direction perpendicular thereto. According to this, the sealing material 4 is cut, and the window glass 1 is cut.
Alternatively, the frame and the side structure 3 are separated. If the holding metal 6 is removed, the window glass unit can be easily removed. If all the seals 4 cannot be cut so that the unit can be removed, a blade is used as an aid, but this is easy.

When one end of the wire 5 does not protrude from the surface, the sealing material 5 at the predetermined position is cut with a knife or the like.
Alternatively, the wire 5 is dug up so that one end of the wire 5 can be gripped with pliers or the like.

When filling the sealing material 4, the wire 5 may be embedded. However, since the purpose of the wire 5 is to cut the sealing material 4, the wire 5 should be as close as possible to the surface of the glass 1 or the outer surface of the packing 2a. Alternatively, a space 2b between the side structure 3 and the packing 2 can be considered.

If a window glass unit in which wires 5 are previously arranged on the surface (outer surface) of the window glass 1 or the packing 2a is attached to the side structure 3, the wires are arranged on the surface at the time of attachment. The determination of the front and back of the unit is facilitated, and erroneous mounting of the unit in the vertical direction can be prevented by checking the position of the end of the wire 5. Therefore, compared to general side window glass, there is no change in appearance, and there is no change in the installation work, and it has the advantage of preventing erroneous mounting, and when removing the side window glass once installed Without using sharp cutting tools such as thin blade knives,
It is possible to carry out work that is easy and much safer with general tools such as pliers and pliers.

The side structure 3 is a frame for substantially attaching a window glass.

As described above, in terms of mounting and appearance of the side window glass, the operation can be performed without any change from the conventional side window glass, and the operation can be completed safely and easily without using a blade when removing the side window glass. For this reason, it can be adopted as a spare part from the middle.

[0018]

According to the present invention, it is possible to replace the side window glass without using a knife-like tool, and use only pliers, thereby enabling an easy, efficient and safe operation. it can.
