Description

[Detailed Description of the Invention] (Field of Application of the Invention) The present invention relates to vehicle windows for railway vehicles, passenger cars, etc., and is particularly applicable to the field of side windows thereof.

(Prior Art) FIGS. 3 to 7 show conventional examples of this type of vehicle window.

In FIG. 3, reference numeral 1 denotes a window frame of a vehicle window, which is appropriately attached integrally with the vehicle body 2. This vehicle window frame 1 includes a frameless elevating window glass 3, which will be described later.
is supported by the balancer 4 and fitted so that it can be moved up and down a predetermined distance.

As will be described further later with reference to FIGS. 4 and 5, the frameless elevating window glass 3, as its name suggests, removes the window frame that reinforces the window glass 5 to increase the daylighting area. Although it is a window glass, a handle member 6 (6a...the handle part) having a substantially U-shaped cross section is simply attached to the upper edge of the window glass 5 with adhesive for raising and lowering the window glass 5, Further, a glass receiving member 7 having a substantially H-shaped cross section is attached to the lower edge of the window glass 5, and the guide roller 4a of the balancer 4 is slid along the guide groove 7a to assist the raising and lowering operation of the window glass 5. At the same time, window glass sliding guide members 8, 8 having a substantially U-shaped cross section are attached to the left and right edges of the window glass 5, and are guided up and down along the guide grooves 9, 9 of the vehicle window frame 1. A moquette 10 installed in the guide member 8 maintains watertightness between the two.

In this way, the frameless elevating window glass 3 can take in more light than the conventional window glass with a frame, has a good appearance, and can be thinner in width and thickness. Furthermore, in order to make these advantages even more remarkable, each of the above-mentioned members 6 to 8 is formed to be as thin and narrow as possible, and for this reason, well-known screw holes for fixing can be provided in each member. First, as shown in FIG. 6, the members 6 to 8 are merely attached to the window glass 5 independently of each other. In particular, the glass support member 7 that supports the window glass 5 has a guide groove 7a for sliding the guide roller 4a of the balancer 4 as shown in FIG. Therefore, both ends of the glass receiving member 7 cannot be fitted into the guide grooves 9, 9 of the vehicle window frame 1, and a considerable gap S must be provided between the opposing edges as shown in FIG. Moreover, even if such a gap S was provided, there was no problem in normal use.

However, if an unexpected accident occurs due to broken window glass while the vehicle is running, each member 6 to 6
8 is only attached to the window glass 5, as shown in FIG. There is a strong possibility that the other members 6 and 8 will be pushed upwards, and as a result of this, the other members 6 and 8 will also come off the guide grooves 9 and 9, and that these will be scattered inside and outside the vehicle interior, causing more damage.

(Problem that the invention attempts to solve) Such accidents occur in each of the above members 6 to 6.
8 are independent from each other, therefore, if each member is integrally connected to each other, accidents such as those described above should be prevented. The problem to be solved by the present invention is to satisfy both of these requirements.

(Means for Solving the Problems) In order to solve the above problems, the present invention, as shown in FIGS. The glass receiving member 11,
Glass sliding guide members 12, 12 are provided on the left and right edges.
In a vehicle window in which a frameless elevating window glass 13 is fitted onto a vehicle window frame 1 so as to be able to rise and fall freely, the opposing edges 10a to 12a of each of the members 10 to 12 are coated with an adhesive or the like 14. Thus, each member is integrally connected in a four-circumference frame shape by gluing, and both end edges of the handhold member 10 are cut out in a horizontal L shape, and tongue pieces 15, 15 are provided that extend horizontally to the end edges.
A structure is adopted in which the upper end edge of the glass sliding guide member 12 is covered with the tongue pieces 15, 15.

(Function) The above-mentioned members 10 to 12 are integrally connected in the shape of a four-periphery frame, so that their positional fluctuations are regulated, and the mutually opposing end surfaces 10a to 12a of each member are directly bonded with adhesive or the like. 14, it is not necessary to make each member 10 to 12 thick and wide.

By covering the upper edge of each glass sliding guide member 12 with each of the tongue portions 15, the upper edge of the guide member 12 is hidden. Also, handhold member 1
When bonding and connecting the opposite edges of each glass sliding guide member 12, the end of the glass sliding guide member 12 is attached to the lower surface of each tongue piece 15 of the handhold member 10 attached to the upper edge of the window glass 5. By bringing the edges into contact, this tongue portion 15 functions as a positioning means, and both the left and right glass sliding guide members 12, 12 are attached to fixed positions.

(Example) The cross-sectional structure of the hand grip member 10 (10b is the hand grip portion) and the glass support member 11, which are attached to the upper and lower edges of the window glass 5 made of tempered glass or semi-tempered glass, is shown in FIG. This is the same as the conventional example, and is formed by extrusion molding of aluminum material, but unlike the conventional example, in this example, both edges of the handhold member 10 are cut out in an L shape, Flat plate-shaped tongue pieces 15, 15 are integrally provided, and the tongue piece 1
5 and 15 are fixed with an appropriate adhesive so as to cover the upper edge of the glass sliding guide member 12. The cross-sectional structure of the glass sliding guide member 12 attached to the left and right edges of the window glass 5 is also the same as that of the conventional example shown in FIG. 5, and is made of a synthetic resin material such as hard vinyl chloride. A moquette (not shown) for watertightness is integrally installed.

And mutually opposing edges 10a to 12a of the members 10 to 12 attached to the peripheral edge of the window glass 5.
An elastic sealing material that also serves as an adhesive, for example, an adhesive 14 that also serves as a putty such as Thiokol (trade name) made by mixing synthetic rubber with epoxy resin or a silicone sealant, is applied in such a manner as to fill the space between the two parts facing each other. Adhere the edges 10a to 12a. In this case, the handhold member 10 and the glass sliding guide member 1
Since the mutually opposing edges 10a and 12a of 2 and 12 are abutted together with almost no gap, before attaching these members to the window glass 5, each edge 10a is
The adhesive 14 may be applied to the glass receiving member 11 and the glass sliding guide member 1.
As shown in the figure, there is generally a gap of about 5.5 mm to 10 mm between the opposing edges 11a and 12a, so it is preferable to apply the adhesive to the gap as described above.

In this way, each member 1 on the peripheral edge of the window glass 5
0 to 12 are integrally connected in a four-circumference frame shape, and as a result of an experiment, a 5 mm thick reinforced steel ball made of this example was strengthened using a pendulum type impact method with a 5500 g steel ball from a position 3 m away. When it was applied to a window glass, each member 10 was damaged due to damage to the window glass 5 as shown in FIG.
The four-circumferential frame shape of ~12 was maintained, and no falling off from the vehicle window frame occurred.

(Effects) According to the present invention, even if the window glass is broken while the vehicle is running, the components attached to the peripheral edges will not fall off from the vehicle window frame, thereby preventing the spread of the accident. can.

Further, according to the present invention, since the upper end edge of the glass sliding guide member is covered by the tongue pieces protruding from both end edges of the handhold member, the upper end edge of the guide member is hidden by the tongue pieces. This improves the appearance, and the tongue piece serves as a positioning means when connecting the handhold member and the glass sliding guide member, so that the handhold member and the glass sliding guide member are The connection work with the motion guide member becomes easier.
