IN VEN TOR.
Patented Dec. 30, 1947 DOOR CONSTRUCTION John J. Kuettel, St. Paul, Minn., assgnor to Herzog Iron Works, Inc., St. Paul, Minn., a corporation of Minnesota Substituted for abandoned application Serial No.
177,628, December 1, 1937.
This application April 1, 1946, Serial N0. 658,631
4 Claims. (Cl. 189-46) This is a substitution of my application Serial No. 177,628, filed December 1, 1937 which application has been abandoned, My invention relates to an improvement in door constructions, wherein it is desired to provide a door 'formed of insulating material and covered with a covering of metal.
It is an object of my invention to provide a door provided with a metallic frame and metallic co'vering and which is provided with insulating sheets inclosed therein in order to prevent ready transmission of sound. The door thus constructed, is rigid and cannot readily get out of shape due to the metallic framework and yet is relatively light in weight and relatively sound-proof.
It is a purpose of my invention to provide a door having a framework formed of metallic channel members and to provide surface covering sheets marginally secured to this channel frame. The extreme edges of the covering sheets are concealed by means of a closing strip which acts to conceal the joint between the covering sheets on opposite surfaces of the door and which provides a construction having the appearance of a single covering sheet extending over both surfaces of the door.
It is a further object of my invention to provide a door having a channel frame which is reinforced by channel members extending from edge to edge of the door between the sides of the frame. These reinforcing members are preferably formed of channel irons or the like, to provide an eX- tremely rigid door construction.
It is an object of my invention to provide a door having a pair of opposed covering sheets secured to a marginal frame and to reinforce this frame by braces which are connected between opposite sides of the frame and which are spaced from the door covering sheets. This construction permits insulating sheets to be used in llling the door which sheets are formed in one piece and extend substantially the entire area of the covering sheets and which are positioned on either sider of suitable cement which holds both sides of the door Y channels 2 together. This construction prevents warping of the metallic covering sheets and holds these relatively thin sheets in proper position;
These and other objects and novel features of my invention will be more fully and clearly set forth in the following specification and claims.
In the drawings forming a part of my specification: f
Figure 1 is a front elevation View of my door in readiness for use.
Figure 2 is a cross-sectional view on the line 2 2 of Figure 1.
Figure 3 is a perspective view of my construction, with the various parts of the door partly broken away to illustrate the construction of the door.
My door A is provided with a frame formed of channels Ill, the central portion I I of which forms the edge of the door and the side flanges I2 of which extend within the inner and outer surfaces of the door. The channels I0 are welded together at the corners to provide a rectangular frame or a frame of any desired shape to form a door of proper size.
Within the channel I0 forming the vertical member of the door adjacent the edge to which the handle and lock I3 are secured, I provide a reinforcing strip I4 which is welded within the member II of the channel Ill.
Cross braces I5 in the form of channels preferably secured on edge so that the side flanges I6 thereof are one above the other, are secured at the ends thereof to the channels IB on the opposite sides of the door. These channels I5 form cross braces for connecting the two vertical channels of the door frame and are substantially narrower when secured on edge as disclosed, than the channels I0, The channels I5 are secured intermediate the flanges I2 of the channel I0, providing a space between these flanges I2 and the I5. Preferably at the bottom of the door A, I provide channels I1 and I9 which extend diagonally from the lower corners of the frame channels I0 to a point adjacent the lowermost cross brace I5. These channels I1 and I9 are welded in position and are connected similarly to the channels I5 to provide a space between these channels and the anges I2 of the channels I0. The diagonal positioning of the channels Il' and I9 prevent any chance of the door A getting out of its proper rectangular shape.
On either side of the channels I5, l1 and I9. I provide sheets 20 of insulating material, or the like. These sheets extend virtually the entire area of the door frame and extend flush with the outer sides of anges I2 of the channels I0. Between the insulating sheets 20, I provide sheets 2I which are cut to t between the cross channels I5 and to lit between the channels I'I and I9. These blocks 2i are of suflicient thickness to ll the space between the blocks to support these blocks or sheets 2li flush with the outer sides of flanges l2 of the channel I0. Suitable cement is provided between the sheets 20 and the blocks 2l or sheets, to hold these various insulating members securely together.
A cover sheet 23 extends entirely'over the outer surface of one sheet 20 and is turned in marginally to form an edge flange 23 which is offset at 24 to closely overlie the portion II of the frame channels I. The offset portion 24 is secured to the channels Ill by drive screws 25 or .by other suitable means.
A covering sheet 26 similar to the sheet 22', extends over the opposite surface of the door and is marginally bent at right angles to form an edge ange 21, having anv offsetI portion 29 which is secured to the channels ID 4by drive screws 30, or other suitable means. These sheets 22- and 26 are preferably cemented to the insulation blocks 2li and to the channel flanges I2 to maintain proper shape and to prevent warping or bulging.
An edgeI strip 3 I- overlaps the edges of the cover ing sheets 22 and 26 and conceals the-heads of the screws 25 and 30. These edge strips 3| are provided with inturned edges 32 which extend adjacent the offset portions 24 and 29 of the covering sheets 22 and 26, and provide the appearance of a continuous covering extending over both surfaces of the door. The edge strip y(il is secured in place by means of screws 33 which extend into the portion II of the channels l!) and through the reinforcing strip I4. The heads of thel sere-ws 33 are preferably llush with the surface of the edge strips 3| as shown. In this way I form a door having a channel frame which cannot well get out oi shape and which is provided with cross braces connecting the opposite sides of the frame. The nterstices between the cross braces are lled with insulating members cemented integrally to insulating sheets on either side of these braces, which in turn are integrally secured to the covering sheets. A door A being covered entirely with metal, but being relatively light and soundproof is in this way formed,
In accordance with the patent statutes, I have described the principles of construction 0f my door, and while I have endeavored to set forth the best embodiment thereof, I desire to have it understood that this is only illustrative of a means of carrying out my invention, and that obvious changes may be made within the scope of the following claims Without departing from the spirit of my invention.
