Abstract
A fully frameless sliding shower door assembly includes a sliding panel of sufficient strength to be fully self-supporting and includes a stationary panel. The need for an upper horizontal header member is eliminated by using an upper guide assembly having a guide which is fixed to the sliding panel and configured to slide about a top edge of the stationary panel. A self-centering roller assembly is attachable to the sliding panel without the need for a rail member. The roller assembly and a track therefore feature matching inverted and non-inverted generally U-shaped profiles. The shower door assembly further features inboard and outboard roller finger guards, as well as a track leveling feature which improves ease of installation.
Claims26
A sliding shower door assembly, comprising:
- a fixed door panel and a frameless movable door panel;
- a roller assembly, the roller assembly being attached to a lower portion of the movable door panel, the roller assembly including a roller having a concave rolling surface;
- a track, the track having a convex rolling surface;
- wherein the concave rolling surface of the roller engages with the convex rolling surface of the track;
- an upper guide assembly, the upper guide assembly comprising a guide block and a clamp assembly, the clamp assembly securing the guide block to the frameless movable door panel, the guide block further including a channel, wherein the fixed door panel is slidably received within the channel;
- wherein the upper guide assembly moves with the frameless movable door panel and slides along a portion of the fixed door panel;
- first and second guards on opposite sides of the roller, wherein the first and second guards prevent a user's fingers and toes from inadvertently being caught between the roller and the track;
- wherein the first guard has an L-shaped cross-section comprising a vertical flange and a horizontal flange wherein the vertical flange is attached to the roller assembly and the horizontal flange is positioned below the roller and underneath an elevated horizontal flange of the track;
- and
- wherein the second guard comprises a raised surface formed on the track.
