Field of the Invention

The present invention relates to a bracket for fixing glass during manual assembly of the glass on the body in automobile manufacturing.

Background of the Invention

When the glass is mounted on the vehicle body, paste material is used. The paste is a material for securing the glass onto the body and it is in a fluid state when it is first used. The paste must contact air and freeze for a certain period of time so that it can perform its fixing duty. During this time, the glass tends to slide down due to its weight. With the sliding of the glass, a gap more than desired is formed between the roof and the glass. Aesthetically, too much space causes bad perception, as well as it causes wind noise. This situation is considered negatively in terms of noise, vibration and harshness (NVH). The wind noise is detected from inside the vehicle cabin and affects the customer negatively.

The Problems Solved with the Invention

The objective of the present invention is to provide a glass stopper bracket which prevents glasses staying angled on the vehicle from going down (falling down) after being mounted on the vehicle and enables to be secured in the desired position. This stop is realized by the pin structure on the bracket, which resembles the hedgehog quills. Since these pins resembling hedgehog quills are movable, the paste on the glass serves to hold the glass until it freezes. When the glass is mounted on the vehicle, firstly the pins in the first rows move down depending on the weight of the glass, and the glass does not slide down further by means of the moving pins in the remaining rows. Therefore, when the glass is mounted on the vehicle, it can be positioned while maintaining the gap dimensions with the surrounding parts at the desired level.

Another advantage of the present invention is that, being different from centering, the pivot pin, which is another centering method, can be used to fix the glass by using one piece instead of two.

Detailed Description of the Invention

A glass stopper bracket developed to fulfill the objective of the present invention is illustrated in the accompanying figures, in which:

Figure 1 is cross-sectional view of stopper bracket mounted on the vehicle. Figure 2 is a representative cross-sectional view of the movable pins, some of which have been crushed by the glass seal and having been introduced into the main body.

The components shown in the figures are each given reference numbers as follows:

1. Stopper bracket

2. Main body

3. Movable pin

4. Extension

5. Tab

C. Glass

F. Seal

P. Glass front plastic

T. Under glass traverse A stopper bracket (1), which prevents the glasses (C) from sliding down and enables to be fixed in desired position, essentially comprises

a main body (2) which has holes formed in more than one row and column thereon,

movable pins (3) which extend in the holes on the main body (2), which are adapted to move back and forth in the holes independently of each other when pressure is applied thereon,

an extension (4) which extends from two opposite sides of the main body (2), one tab (5) which is provided at each end of the extensions (4) for securing the main body (2) to the under glass traverse (T) on the vehicles.

The mounting and operating principle of the stopper bracket (1) according to the invention is as follows; firstly, the stopper bracket (1) is fixed to the under glass traverse (T) provided on the vehicles by means of the tabs (5) such that all the movable pins (3) on the main body (2) will be outside. After the process of applying paste performed for securing the glass (C), the glass (C) is placed on the glass front plastic (P) such that the seal (F) of the glass (C) on which the seal (F) is mounted will contact the movable pins (3) on the main body (2).

The glass (C) mounted in an angular way to the vehicle tends to slide downwards due to its weight. The seal (F) connected to the glass (C) is stopped by means of the movable pins (3) in more than one rows and columns formed as hedgehog quill structure which has the ability to slide inside the main body (2) through the holes (not shown in figures) made on the main body (2). The diameter of said holes is almost equal to the diameter of the movable pins (3) and prevents the movable pins (3) from moving downwards with the effect of gravity when no pressure is applied to the movable pins (3).

When the glass (C) is mounted, it pushes the (maximum) two rows of movable pins (3) downwards and stops due to the strength of the movable pins (3) collectively. Therefore, the glass (C) can no longer go down and the said paste begins to freeze. Since the sliding of all glasses (C) fixed by means of the stopper bracket (1) hare the same, in other words all glasses (C) will stay in the same position, the space between the roof and the glass (C) remains the same in all glasses (C) and remains fixed.

In a preferred embodiment of the present invention, there are movable pins (3) in eight rows and seven columns on the stopper bracket (1) which prevents the glass (C) from sliding, however the invention is not limited thereto, the number of rows and columns may be more or less. Also in this embodiment, the glass (C) can slide downward on the movable pins (3) by crushing a maximum of two rows of movable pins (3). The glass (C) stops after two rows of movable pins (3) since it cannot overcome the strength of the remaining movable pins (3).
