7 claims. (ol. 20-69) The invention relatesfto improvements in insulation for doors.
One object of the invention is to provide means for insulating doors and especially the hinged doors lof refrigerator railway cars, comprising a composite strip of insulatingmaterial of simple design, which may be applied as a unit to the doors or door frame.
A more specific object of the invention is to provide a prepared, completely assembled unit insulating strip which may be readily applied by unskilled labor through simply placing the same in position and securing it by a nailing strip or element.
A further object of the invention is to provide a prepared strip of insulation for refrigerator car doors, comprising as a unit a sheet of insulating material, a resilient backing, and a cover strip for the insulating material, together with nailing strip means for securing the unit to the door or doorframe.
Other objects of the invention vwill more clear-1 ly appear from the ldescription and claims hereinafterfollowing. i
In the drawing, forming a partrof this specification, Figure 1 vis a horizontal/sectional View through the hinged double doors and door frame of a refrigerator ear, showing my improvements in connection therewith.v Figure v2 is a view sim` ilar to Figure 1,- on an enlarged scale, showing one wall of the door frame with the improved insulating material applied thereto. Figure 3 is a partly elevational Aand partly vertical sectional view looking from'the right in Figure 2. vAnd Figures 4 and 5 are views similar to Figure 2, illustrating respectively two `additional embodiments of theA invention. l
Referring first to the embodiment of the invention illustrated inFigures 1, 2, and 3, 10--10 indicate the side walls of the door opening ofa refrigerator car, and 11 and 12 `the two hinged doors. As shown, the end edge faces of the walls 10-10 are provided with the usual vertical grooves 13-13, which are adapted to 'accommodate the insulating material strips A-A. The meeting edges of the doors 11 and 12 are beveled as usual, and the door 12 is shown as also provided with a groove 13 in which the insulating v.strip A is seated. As shown in Figures ,1, 2, and 3,
my improved insulation A is in the form of a unit vseated in the groove 13v of either of the'walls Figures Zand 3, the unit Ay comprises a resilient metal strip 14 of curved cross-section having its outer edges curled inwardly, as indicated at 15-15. The resilient strip 14 is enclosed on all sides by a strip of flexible insulating material 16, which is preferably in the form of quilting. As most clearly shown in Figure 2, the quilting materialhas an indented section 17 disposed centrally between the curled edge portions 15-15 of the metal strip 14. The metal strip 14 and the strip of exible insulating material 16 are enclosed within a fabric sheathing 18, which is preferably made of canvas and has a side'seam, as indicated at 19, which is preferably stitched. The exterior contour of the sheathing 18 corresponds tothe exterior contour of the flexible insulating material 16. The resilient strip 14 together with the insulating strip 16 and the sheathing 18 form the complete unit of insulating material, which is bodily applied within the groove 13. In placing the insulating unit A within the groove 13, the convex side thereof is disposed next adjacent to the inner vertical Wall of the recess or groove. In order to fasten the unit A within the groove 13,*a nailing strip 20, preferably of wood, is placed within the seat formed by the indented portion of the unit between the curled side edges 15--15 'of the strip 14, and the unit is thereby clamped within the recess or 'groove 13. Securing elements in the form of a plurality of nails y'21 are preferably employed for fixing the unit A in position, the nails 21 extending through the securing strip 20, the sheathing 18, the flexible insulating material 16, and the resilient strip 14, and into the member provided with the groove 13. When the unit strip A is secured within the grooved member, the same projects outwardly beyond the end edge face of said member so that it will engage the cooperating door member when closed. The material of the insulation A projects to such an extent that the unit Will be compressed when the doors are closed, thereby providing a tight seal betweenthe opposed edge faces of the overlapped door members.
Referring next to the embodiment of the invention illustrated in Figure 4, the same comprises a unit insulation member B, including a central resilient metal strip 22, which is curved in cross-section and has the convex side thereof member; of la pair of nailing strips covering the side edges of said unit; and securing means extending through said nailing strips, the side edges of the fabric covering strips, and the side edges of the exible insulating strip.
'7. In means for insulating closures of containers, the combination with a closure member having an edge face; of a -cooperating member also having Ian edge face, said members being relatively movable to bring said edge faces of said members in opposed relation, the edge face of one of said members being longitudinally grooved; a strip of insulating material having
