Ceiling suspension system

Inventors: Reina Briceno, Enrique;

Attorney, Agent or Firm:
A ceiling suspension grid system is provided in which cross tees are assembled to main beams by pushing tabs in the web of one through a corresponding slot in the web of the other. The slots and webs are vertically oriented. Each slot is provided intermediate its height with at least one wide place of comparatively small vertical extent. The tabs are provided with correspondingly thickened bosses, but at slightly vertically displaced sites, so that two elements which are to be connected are oriented at slightly different levels so that the tab of one may be inserted through the slot of the other. Then, upon these elements being brought to a common level, the tab cannot be withdrawn from the slot. By preference, the tabs of two longitudinally adjoining elements may be inserted in the same slot from opposite directions, and become disposed one over the other with the element ends being notched to accommodate the tabs of one another. Bracing fingers preferably are provided on these element ends to rigidify the assembled gridwork. The slots may be provided with two, vertically spaced wide spots, in order to facilitate disconnection of one of the elements from the crossing element without requiring disconnection of the respective longitudinally continuing element from the crossing element at the same slot. |

DETAILED DESCRIPTION It is an object of the invention to provide a system of gridwork for a suspended ceiling, where the individual elements are comparatively easy to assemble while working overhead, and where if mistakes are to be corrected, defective elements to be replaced, or changes to be made, the remedial effort is comparatively easy to accomplish and few or no elements are necessarily destroyed in the course of making the changes.
A ceiling suspension grid system is provided in which cross tees are assembled to main beams by pushing tabs in the web of one through a corresponding slot in the webs of the other.
The slots and webs are vertically oriented.
Each slot is provided intermediate its height with at least one wide place of comparatively small vertical extent.
The tabs are provided with correspondingly thickened bosses, but at slightly vertically displaced sites, so that two elements which are to be connected are oriented at slightly different levels so that the tab of one may be inserted through the slot of the other.
Then, upon these elements being brought to a common level, the tab cannot be withdrawn from the slot.
By preference, the tabs of two longitudinally adjoining elements may be inserted in the same slot from opposite directions, and become disposed one over the other with the element ends being notched to accommodate the tabs of one another.
Bracing fingers preferably are provided on these element ends to rigidify the assembled gridwork.
The slots may be provided with two, vertically spaced wide spots, in order to facilitate disconnection of one of the elements from the crossing element without requiring disconnection of the respective longitudinally continuing element from the crossing element at the same slot.
The principles of the invention will be further discussed with reference to the drawings wherein preferred embodiments are shown.
The specifics illustrated in the drawings are intended to exemplify, rather than limit, aspects of the invention as defined in the claims
