Rail assembly for a glass door
A rail assembly for a glass door has a rail body, two clamping members, a pushing member and at least one pushing bolt. The rail body has a clamping channel defined in and along the rail body. The clamping members are movably mounted in the clamping channel. Each clamping member has a clamping recess and an inclined guiding surface. The clamping recess is defined in the clamping member at a side facing to the other clamping member. The inclined guiding surface is defined in the clamping member at a side opposite to the other clamping member. The pushing member is mounted movably in the clamping channel, holding the ends of the clamping members inside and has two inclined surfaces abutting respectively with the guiding surfaces of the clamping members. The least one pushing bolt is screwed into the rail body and pushes against the pushing member.
1. A rail assembly for a glass door, comprising:
an elongated rail body having
a clamping channel defined in and along the rail body; and
an opening defined in and along the rail body and communicating with the clamping channel;
two elongated clamping members movably mounted in the clamping channel, and each clamping member having
a clamping recess defined in the clamping member at a side facing to the other clamping member; and
an inclined guiding surface defined in an end of the clamping member at a side opposite to the other clamping member;
an elongated pushing member mounted movably in the clamping channel, holding the ends with the inclined guiding surfaces of the clamping members inside and having
two inclined surfaces defined in the pushing member and abutting respectively with the guiding surfaces of the clamping members; and
at least one pushing bolt screwed into the rail body and pushing against the pushing member, wherein
the opening of the rail body has
two sides facing to each other; and
two guiding ribs formed respectively on the sides of the opening to define a guiding channel between each guiding rib and the opening; and
each clamping member further has a holding channel defined in the clamping member at the side opposite to the clamping recess and slidably holding one of the guiding ribs on the rail body inside to form a guiding flange slidably held inside a corresponding guiding channel in the rail body.
2. The rail assembly as claimed in claim 1 , wherein the rail body has an H-shaped cross section and a baffle rib at a middle of the rail body;
the baffle rib having at least one threaded hole defined through the baffle rib and screwed respectively with the at least one pushing bolt; and
the clamping channel is defined inside the rail body at one side of the baffle rib.
3. The rail assembly as claimed in claim 2 , wherein the guiding surfaces of the clamping members have an inclination same as that of the inclined surfaces on the pushing member.
4. The rail assembly as claimed in claim 3 , wherein the rail body further has two caps attached respectively to two ends of the rail body.
5. The rail assembly as claimed in claim 4 , wherein each clamping member further has a clamping element held in the clamping channel of the clamping member.
6. The rail assembly as claimed in claim 5 , further comprising an elongated pushing strip mounted between and abutting with the pushing member and the at least one pushing bolt.
7. The rail assembly as claimed in claim 6 , wherein the pushing member has a U-shaped cross section.
8. The rail assembly as claimed in claim 1 , wherein the guiding surfaces of the clamping members have an inclination same as that of the inclined surfaces on the pushing member.
9. The rail assembly as claimed in claim 1 , wherein the rail body further has two caps attached respectively to two ends of the rail body.
10. The rail assembly as claimed in claim 1 , wherein each clamping member further has a clamping element held in the clamping channel of the clamping member.
11. A rail assembly for a glass door, comprising:
an elongated rail body having
a clamping channel defined in and along the rail body; and
an opening defined in and along the rail body and communicating with the clamping channel;
two elongated clamping members movably mounted in the clamping channel, and each clamping member having
a clamping recess defined in the clamping member at a side facing to the other clamping member; and
an inclined guiding surface defined in an end of the clamping member at a side opposite to the other clamping member;
an elongated pushing member mounted movably in the clamping channel, holding the ends with the inclined guiding surfaces of the clamping members inside and having
two inclined surfaces defined in the pushing member and abutting respectively with the guiding surfaces of the clamping members;
at least one pushing bolt screwed into the rail body and pushing against the pushing member; and
an elongated pushing strip mounted between and abutting with the pushing member and the at least one pushing bolt.
12. The rail assembly as claimed in claim 1 , wherein the pushing member has a U-shaped cross section.
