Ceiling system

1. A ceiling system comprising:

a longitudinally extending grid support member defining a longitudinal axis, the grid support member including a bottom flange, a top stiffening channel, and a vertical web connecting the stiffening channel to the bottom flange;

a ceiling panel;

a torsion spring mounted on the ceiling panel;

a spring clip slideably mounted on the grid support member and movable in opposing axial directions, the spring clip comprising a mounting portion, a pair of lateral flanges extending laterally outwards in opposing directions from the mounting portion, and a pair of resilient locking tabs, the pair of lateral flanges engaging and retaining the torsion spring;

the pair of resilient locking tabs engaging the grid support member on opposing sides of the vertical web, each of the locking tabs located below a bottom surface of the top stiffening channel and configured to engage the bottom surface of the top stiffening channel to vertically lock the spring clip to the grid support member;

wherein the locking tabs are symmetrically centrally arranged on the clip and spaced inwards from opposing ends of the clip such that each tab is diametrically opposite the other tab;

wherein the locking tabs are formed as an integral bent portion of each lateral flange; and

wherein the ceiling panel is supported from the grid support member by the torsion springs.

2. The ceiling system of claim 1 , wherein the locking tabs each project inwards to engage the grid support member.

3. The ceiling system of claim 1 , wherein the spring clip includes an elongated slot that engages the torsion spring.

4. The ceiling system of claim 3 , wherein the torsion spring includes a coil and two resilient arms.

5. The ceiling system of claim 4 , wherein the arms of the torsion spring are engaged with the slot of the spring clip to retain the torsion spring.

6. The ceiling system of claim 1 , wherein the spring clip is formed of an elastically deformable resilient material, the locking tabs being laterally deflectable when mounting the spring clip on the grid support member.

7. The ceiling system of claim 1 , wherein the locking tabs are disposed at an angle with respect to the flanges.

8. The ceiling system of claim 1 , wherein the spring clip is snap-fit onto the grid support member.

9. The ceiling system of claim 1 , wherein the grid support member has a T-shaped cross-section.

10. The ceiling system of claim 1 , wherein the locking tabs are separated by a lateral distance less than a lateral width of the top stiffening channel.

11. A spring clip for mounting ceiling panels equipped with torsion springs to a ceiling support grid, the clip comprising:

a body including a mounting portion defining a downwardly open receptacle configured for attachment to a ceiling grid support member;

a pair of lateral flanges extending outwards from the mounting portion, at least one of the flanges including a slot configured to engage a torsion spring;

a pair of resilient locking tabs disposed on the spring clip, the locking tabs configured to engage opposing sides of the grid support member, the locking tabs connected to and extending from an edge of a respective one of the lateral flanges;

wherein the locking tabs are symmetrically centrally arranged on the clip and spaced inwards from opposing ends of the clip such that each tab is diametrically opposite the other tab;

wherein the locking tabs are formed as an integral bent portion of each lateral flange;

wherein the locking tabs are laterally deflectable in opposing directions when attaching the spring clip onto the grid support member and lock the spring clip to the grid support member; and

wherein the mounting portion comprises spaced-apart vertical sidewalls, each of the spaced-apart vertical sidewalls comprising an aperture located adjacent to and above a respective one of the locking tabs.

12. The spring clip of claim 11 , wherein the spring clip is slidable when locked onto the grid support member.

13. The spring clip of claim 11 , wherein the locking tabs are trapped beneath a bottom surface of the grid support member to lock the spring clip to the grid support member.

14. A ceiling system comprising:

a longitudinally extending grid support member defining a longitudinal axis, the grid support member including a bottom flange, a top stiffening channel, and a vertical web connecting the stiffening channel to the bottom flange;

a ceiling panel;

a torsion spring mounted on the ceiling panel;

a spring clip slideably mounted on the grid support member and movable in opposing axial directions, the spring clip comprising a mounting portion, a pair of lateral flanges extending laterally outwards in opposing directions from the mounting portion, and a pair of resilient locking tabs, the pair of lateral flanges engaging and retaining the torsion spring, each of the locking tabs located below a bottom surface of the top stiffening channel and configured to engage the bottom surface of the top stiffening channel to vertically lock the spring clip to the grid support member; and

wherein the ceiling panel is supported from the grid support member by the torsion springs; wherein the mounting portion comprises spaced-apart vertical sidewalls, each of the spaced-apart vertical sidewalls comprising an aperture located adjacent to and above a respective one of the resilient locking tabs.

15. The ceiling system of claim 14 , wherein the resilient locking tabs are connected to and extend from an edge of a respective one of the lateral flanges.

16. The ceiling system of claim 14 , wherein the spring clip is formed of an elastically deformable resilient material, the locking tabs being laterally deflectable when mounting the spring clip on the grid support member.

17. The ceiling system of claim 14 , wherein the locking tabs are disposed at an angle with respect to the flanges.
