Serial No. 569,797
This invention reiates to'refrigerator cabinets and the like and more especially to an improvement in the construction thereof pertaining particularly to the connection between the inner and 5 outer panels thereof at the periphery of the door opening of the cabinet.
In the prior art it has -generally been customary to insulate the inner and outerpanels from one another at the juncture thereof by finish prevent the transference of lheat from the outer to the inner panel such as would result if these panels had a metal-to-metal contact. In the use of bakelite, wooden or other types of finish strips, such as previously used, it has been necessary to employ a large number of attaching elements such as screws or the likein order to A hold these finish strips or plates in place, by reason of their fragile character pr nature.
In accordance with this invention I propose employing a metal finish member which may be secured in place by a relatively small number of securing elements and I eliminate the objectionable metal-to-metal contact of the parts by the 25 use of a gasket member or sealing strip which also provides a second sealing member between the door and cabinet.
The several objects, advantages and novel details of construction of the invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein Figure 1 is a perspective view of a cabinet constructed in accordance with this invention;
opening therefore and through the door, the latter being in closed position;
' Figure 3 is a similar view showing the cabinet and door in vertical section;
Figure 4 is an enlarged fragmentary sectional View through the door and cabinet at the juncture thereof;
Figure 5 is a perspective view of the nish plate or member, and
Figure 6 is a view similar to Figure 4 of a slightly modied form of construction.
Before explaining in detail the present invention it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the linvention is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understood that the phraseology or strips or plates of bakelite or other material to Figure 2 is an enlarged horizontal fragmentaryv sectional view tirougl: the cabinet at the door- (cl. zzo-9) terminology employed herein is for the purpose of description and not of limitation. and it is not intended to limit the claimed invention herein beyond the requirements of the prior art.
Referring now more especially to the drawings 5 wherein like reference characters indicate like parts, it will be noted that there is illustrated a cabinet Ill provided with a door II, the cabinet being provided with the customary cooling unit I2 such as is employed inthe standard types of l0 domestic mechanical refrigerators.
The door I I comprises an inner metal panel I3 and an outer metal panel Il, the door being provided with side frame members" I5 and being insulated by an insulating material I6. Secured in the rabbet I1 of the door and extending peripherally thereof is a sealing gasket I3, the latter being preferably secured in place by engagement between the face of the rabbet II and the edge I3 of the inner panel I3. 'I'his gasket I8 provides 20K an outer'seal between the door II and the door opening of the cabinet III.
The cabinet proper comprises inner panels 2li and outer panels 2l, both of sheet metal. In practice it is essential that these two metal panels` and 2l be insulated from one another so as to eliminate any metal-to-metal contact' thereof which would cause the heat at the exterior of the cabinet being conducted .to the interior thereof.
In accordance with this invention this is accomplished, and the juncture between the adjacentedges of' these two panels is covered and finished by means of a finish plate or strip 22.
This nish plate or strip may be of single thickness or may comprise portions doubled over upon `itself as illustrated.. Thev nish plate or strip is preferably constructed in the form of a. frame such as illustrated in Figure 5, the nish plates for the four sides of the door opening being permanently united at their junctures 23 as, for instance, by means of welding, to provide a substantial frame-like member which may be secured to the cabinet structure as a. unit.
In order to insulate the inner panel 20 from 45 the outer panel 2| so as to prevent the conducting of heat from one to the other through the nish plates 22, I provide a gasket member 24 which has a portion 25 thereof arranged-between the edges 26 of the inner panels 23 and the ad- 50 jacent edges of the finish plates 22. This gasket 24 thus not only acts as an insulating medium between the panel 2li and the finish strip 22 but' also provides a gasket affording an inner seal between the door II and the cabinet structure. U5.'
ltures 28 in the nish'plates and into the insulating material 29 located between the inner and outer panels 20 and 2| of the cabinet.
In Figure 6 a slightly modified form of construction is illustrated in which the finish strips 22 are secured in place by means of metal screws 30 which are passed through apertures located adjacent the edges of the finish strips and are screwed into pierced apertures 3| formed in the edges 26 of the inner panels 20 and in the edges 32 of the outer panels 2| In al1 other respects the structure illustrated in Figure 6 is substantially similar to that illustrated in the remaining gures of the drawings. l
What I claim as my invention is: l
1. A cabinet structure of the class described having inner and outer metallic panels which terminate in spaced longitudinal edges at the door opening of the cabinet, a door for said opening, an air sealing gasket disposed between the door opening of said cabinet and the said door when the door is in closed position, a nish plate overlapping the spaced edges of said panels, an auxiliary air sealing gasket clamped between the overlapping portions of one of said panels and the iinish plate and constituting a second air sealing gasket between said door and said cabinet when the door is in closed position.
2. A cabinet structure of the class described having inner and outer metallic panels which terminate in spaced longitudinal edges at the door opening of the cabinet, a door for said opening, an air sealing gasket carried by the door and disposed between the door opening of said cabinet and the said door when the door is in closed position, a iinish plate overlapping the spaced edges of said panels, and an auxiliary air sealing gasket clamped between the overlapping portions of one of said panels and the finish plate and constituting a second air sealing gasket between said door and said cabinet when the door is in closed position.
