Folded ceiling baffle

Abstract

In one aspect, a folded ceiling baffle is constructed from a sheet of felt. For example, in a particular implementation, the folded ceiling baffle is constructed from a sheet of felt having respective portions of shape and size that may be folded to form the ceiling baffle.

1 . A folded ceiling baffle constructed from a sheet of felt, the baffle, in its folded state, including:
 an elongate base having an elongate first edge and an elongate second edge opposite to the elongate first edge;   a first elongate side folded from the elongate base and extending from the first edge to a first top edge;   a second elongate side folded from the elongate base and extending from the second edge to a second top edge, the second elongate side facing the first elongate side;   a first top portion folded from the first elongate side and extending from the first top edge;   a second top portion folded from the second elongate side portion extending from the second top edge towards the first top portion;   a planar first end part folded from the first elongate side at one end of the baffle and extending from a first side edge of the first elongate side to a first inner edge;   a planar second end part folded from the second elongate side at the one end of the baffle, extending from a second side edge of the second elongate side to a second inner edge, and aligning with the first inner edge so that the first and second end parts are coplanar in order to together form a planar end portion at the one end of the baffle; wherein:   the first end part includes a protrusion extending from the first inner edge and coplanar with the first end part;   the second end part includes a space extending inwardly from the second inner edge; and   the protrusion is received in the space and retains the first end part and the second end part together to form the planar end portion.   
     
     
         2 . A folded ceiling baffle according to  claim 1  further including:
 a first inner flap folded from the first end part and extending from the first inner edge inwardly of the ceiling baffle; and 
 a second inner flap folded from the second end part and extending from the second inner edge inwardly of the ceiling baffle; wherein 
 the first and second inner flaps have, respectively, first and second planar surfaces that face each other. 
 
     
     
         3 . A folded ceiling baffle according to  claim 2  wherein the first and second planar surfaces contact and engage with each other. 
     
     
         4 . A folded ceiling baffle according to  claim 2  wherein the protrusion of the first end part is a cut-out from the first inner flap. 
     
     
         5 . A folded ceiling panel according to  claim 1  wherein the protrusion is narrower at the first inner edge than at at least one portion distal from the first inner edge. 
     
     
         6 . A folded ceiling panel according to  claim 1  wherein sides of the protrusion are angled away from one another. 
     
     
         7 . A folded ceiling baffle according to  claim 1  wherein the protrusion has a dovetail shape. 
     
     
         8 . A folded ceiling baffle according to  claim 1  wherein the protrusion and the space have complimentary dimensions. 
     
     
         9 . A folded ceiling baffle according to  claim 1  wherein the space is completely filled by the protrusion. 
     
     
         10 . A folded ceiling baffle according to  claim 1  wherein the space is defined by surrounding edges of the second end part and the protrusion resiliently engages with the surrounding edges and is held frictionally within the space. 
     
     
         11 . A folded ceiling baffle according to  claim 1  in combination with an elongate support element having a first elongate support edge to which the first top portion is connected and a second elongate support edge to which the second top portion is connected. 
     
     
         12 . A folded ceiling baffle according to  claim 11  wherein, between the first elongate support edge and the second elongate support edge, the elongate support element has an elongate support portion extending parallel with the first elongate support edge and the second elongate support edge and configured to receive mounting means for supportively suspending the folded ceiling baffle. 
     
     
         13 . A folded ceiling baffle according to  claim 12  wherein the elongate support portion has a lipped channel cross-section. 
     
     
         14 . A sheet of felt formed with respective portions of shape and size to form the parts of the ceiling baffle of  claim 1 . 
     
     
         15 . A sheet according to  claim 14  including recesses in the thickness of the sheet defining fold lines between respective parts of the ceiling baffle.
