BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a slide brake unit which is mounted on a slide hinge apparatus slidably supporting a glass door to absorb impact.

Currently, glass booths using glass doors are installed and used in many apartments, single-family homes and exhibition halls. Particularly, since the shower booth, which is an example of the glass booth, can prevent water from splashing during the shower, the use of the shower booth is further increasing for the purpose of implementing a dry bath. The construction of such a glass booth is accomplished by installing a frame on a wall in advance, and then installing a glass panel and a glass door on the frame. At this time, the glass door is coupled by a hinge provided on one side of the wall or frame, .

However, in the case of a glass door pivoted by a hinge, a space is required for the glass door to pivot so that it is difficult to install the glass door if the sufficient space can not be guaranteed.

Therefore, in order to overcome such a problem, a slide hinge device for a glass door has been developed in which a guide rail is provided on an upper portion of a wall and moved along the guide rail. The slide hinge device opens or closes the passageway while supporting the glass door.

However, since the inertia due to its own weight occurs when the glass door is slid, a lot of impact is applied when the slide hinge device for supporting the glass door is stopped at the end of the guide rail or the wall. Accordingly, the slide hinge device must be equipped with a bumper capable of absorbing impact applied thereto. Accordingly, in addition to the development of the slide hinge device, a lot of research and development has been conducted on the bumper.

The glass door G is moved by its inertia due to its own weight and then strikes against the fixed bumper B of the fixed bar F and stops. At this time, an impact is generated in the glass door G. Part of the impact is absorbed in the fixed bumper B, but the rest acts as a repulsive force on the glass door G.

The repulsive force acts in the direction in which the glass door G is opened. At this time, the repulsive force is more transmitted to the lower side of the glass door by the brake unit supporting the glass door, and as shown in Figs. 12 and 13, G) is raised. 13, the slide hinge device S 'for supporting the rear side of the glass door is lifted, whereby the brake pads 120' of the brake stage 111 'on the side of the slide hinge device S' Is brought into close contact with the brake rail R1 so that the glass door G can not be opened while absorbing the remaining repulsive force.

Meanwhile, when the glass door is moved to the opposite side in order to open the glass door, the glass door hits a fixed bumper (not shown) fixed to the rear side, and the slide hinge device S supporting the front side of the glass door by the above- The brake pad 120 of the brake stage 111 will be in contact with the brake rail R1 while the brake unit is operated, so that it will absorb the shock.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

As described above, the slide brake unit according to the present invention absorbs impact generated when the glass door is closed, thereby preventing the glass door from being opened again by the repulsive force of the impact.
