- 7% v 2 4,989 a Y I noon MOUNTING I Ralph c. Parkes, Philadelphia, Pa. v Application January 24, 1952, Serial No. 268,067
'1 Claim., (Cl. 220-16) In the construction of drying chambers and the walls and the bodies of the .doors of such chambers are heavily insulated. However, there is considerable heat loss around the door frame and it is one object of my invention to produce an improved door mounting whereby heat loss around and through the door and the door frame is greatly reduced.
In order to insure an air tight joint, and in order to minimize heat loss by conduction, I mount a gasket, or its equivalent, such as weather stripping, on the door frame and I provide the inner side of the door with an inwardly projecting lip which, when the door is closed tightly, will form an indentation in the gasket or the weather stripping. With this construction I found that, as a conventionally mounted door is swung open, the inwardly projecting lip will move in an arcuate path and will cut, scrape and otherwise damage the gasket.
It is therefore a further, object of the invention to produce an improved door mounting whereby, when being opened, or shut, the door is bodily moved away from, or towards, the door frame so to to disengage the said inwardly projecting lip from the gasket or the weather strippingbefore the door. begins a; swing on its hinges thereby preventing :all damage to the gasket. I
These and other objects are attained by my invention as set forth in the following. specification and the accompanying drawings inwhich:
Fig. 1 is a front elevational View of a door mounting embodying my invention. v
Fig. 2 is an enlarged sectional view looking in the direction of line 22 on Fig. 1 showing the position of the parts when the door is closed.
Fig. 3 is an enlarged sectional view looking in the direction of line 3-3 on Fig. 1.
Fig. 4 is similar to Fig. 2 showing the position of the parts when the door is unlatched but before it is swung open.
Fig. 5 is an enlarged sectional view looking in the direction of line 5-5 on Fig. 1.
Fig. 6 is an enlarged sectional view looking in the direction of line 6-6 on Fig. 1.
Fig. '7 is an enlarged sectional view looking in the direction of line 'I--! on Fig. 1.
Fig. 8 is a sectional view looking in the direction of line 8-8 on Fig. 1.
Fig. 9 is an enlarged, fragmentary sectional view showing the use of weather stripping on the door frame instead of a gasket.
In the drawing there is shown a portion) of the insulated wallof a drying chamber,a door frame l2 which defines an access opening leading into the drying chamber and a doorl4 for closing said opening; The door frame [2 includes vertical and horizontal angles 15 and I6, Figs. 2 and 7, and inner and outer spacing'blocks l8 and i9 and is secured. in position by means of bolts 20 which engage hinge plates 22 and pass through the spacing 'blocks l8 and [9,.
through angle l6 and throughtheouter sheathing 24. The hinge plates 22 carry pintles 26 which are adapted to be engaged by sleeves 28 which are carried by arms 30 secured to the ,door proper as at 32. In this way, the door frame is mounted on the drying chamber wall and the door itself is hinged to the door frame.
In order to provide an air tight joint and in order to minimize conductive heat loss, I provide an auxiliary frame '36 which is secured to the vertical and horizontal angles l5 and I6 and which extends along the entire perimeter of the door frame as can be seen from the various sectional views. As shown in'Figs. 1 to 8, the'auxiliary frame 36 carries a heat insulating gasket .a continuous inwardly projecting lip 40 which,
when the door is closed, is jammed into the gasket38 and forms a seat.,4l asbestshown in: Fig. 4. It will be understood that the inwardly projecting lip. 40 is coextensive withthe gasket 38 so that, when the door is closed, a continuous seal is formed'byfthe engagement of the lip 40- with the groove 4J as. can be seen from Figs. 2 and. '7. The door is held in closed position, and its inner lip 40 is forced into gasket 38 by means of left hand latches 44 and right hand latches 46 which are pivoted as at 48 to the door frame and which are adapted to'ride on cams 50- carried by the door. As Will be seen from Figs. 3 and 5, the latches 44 are carried by, and are adapted to swing, in a vertical plane about,pivot pins 48 and are tensioned by compression springs 52 interposed between the door frame and the end of the latch which is engaged by the pivot pin 48. The righthand latches 46 are, except for their reversed position, identical with left hand latches 44. This will be clearly seen from Fig. 6 in which the latches 46 are carried by and are adapted to swing about pivot pins 48' and are'tensioned by'compression springs 52'. Thus, when the door is closed, and when the latches are in theposition of Figs. 1 and 3 3 and 6, the lip 40 will be pressed into the gasket 38 shown in most of the sectional views.
It will be evident from inspection of Fig. 2, for example, that, when the door is swung about its hinges to the position shown in broken lines in Fig. 4, the lip 40 on the left hand side of the door will move arcuately, and in so doing it will damage, or will wholly remove the portion of the gasket 38 which is to the right of the groove 4| as viewed in Fig. 4. If this takes place, the air tight joint will be destroyed.
In order to overcome this difficulty the bolts 20 which secure the door frame I! to the wall of the drying chamber are passed loosely through the wall of the chamber and through spacing blocks I8 and I9 and through the vertical angle Hi, and they are made somewhat longer than the thickness of the door frame.
Thus, and as will be seen from Figs. 2, 5 and 6, when the door is closed and latched tight, with the sealing lip 40 on the inside of the door engaging groove 4| in gasket 38, the inner heads 54 of bolts 20 will be spaced inwardly of the inner block l8. This construction allows the door to move, bodily, toward or away from the door frame.
In order automatically to move the door away from the door frame as soon as the latches 44 are moved out of engagement with their respective cams, compression springs 56 are interposed between the door frame and the adjacent ends of the hinge plates 30, as will be seen from Figs. 2, 5 and 6. By this construction, as soon as the latches 44 are disengaged, springs 56 push the door outwardly or from the position of Fig. 2 in which the inner lip 40 on the inside of the door engages the groove 4| in the gasket 38, to the position of Fig. 4 in which the lip 40 clears the gasket 38. If the door is now swung about its hinges to the position shown in broken lines in Fig. 4, the lip 40 will follow the broken line 58 and will therefore clear the gasket 38. When the door is to be closed, it is swung into closed position and the application of latches 44 and 45 forces the door into the rightly sealing position shown, for example, in Figs. 2, 6 and '7.
The gasket 38 not only serves to form an air tight joint but, because of its low heat conductivity, it minimizes the conductive heat loss which would take place if'the inner lip- 40, or some other highly conductive part of the door were to abut the door frame which is exposed to the heat within the chamber.
From the foregoing it will be seen that my invention resides, primarily, in the provision of a door which, when being closed, is movable, bodily. into tight engagement with a heat insulating packing, so as to permit the lip on the inner side of the door to enter the packing, and which, when being opened, moves bodily, away from the packing, before the door is swung on its hinges to prevent the lip 40 from damaging the packing. The invention secondarily resides in the mechanical expedients by means of which the primary invention is carried'out.
Since the groove 4| i relatively shallow the springs 56 may or may not be used at the right hand portion of the door, as viewed in Fig. 1.
In the embodiment of Fig. 9 I use Weather stripping formed of a resilient material and bent to form a V-shaped groove which is adapted to receive the lip 40 on the inner side of the door. The material of the weather stripping is preferably of a low thermal conductivity such as plastic or fiber board or molding or the like.
What I claim is:
A frame including vertical stiles and upper and lower sills defining an opening, a door for closing said opening, vertically spaced bolts carried by, and slidable transversely of, one of said vertical stiles, hinge plates carried by the outer ends of said bolts, compression springs carried by said bolts and disposed between said hinge plates and the outer face of said vertical stile, means for limiting the movement of said bolts relative to said stile, arms carried by said door with their ends overlying said stile, means pivotally securing the ends of said arms to said hinge plate hingedly to mount said door on said stile, a pair of horizontally spaced bolts carried by, and slidable transversely of, the opposite vertical stiles, a pair of handles rotatably secured at their ends to the outer ends of said horizontally spaced bolts, compression springs carried by said horizontally spaced bolts and disposed between the ends of said handles and the outer sides of said vertical stiles, and cams carried by adjacent portions of said door and adapted to be engaged to said handles.
