MAGNETIC DOOR SEAL Lloyd L. Anderson and Nathan S. Waring, Grand Rapids, and Anton W. Korb, Grandville, Mich., assignors to Jervis Corporation, a corporation of Michigan Application March 27, 1950, Serial No. 152,244
7 Claims.
This invention relates to improvements in magnetic door closures and seals, being particularly concerned with practical means for releasing and opening a door which is held in closed and securely sealed position by magnetic attraction.
The present invention is designed for use in connection with refrigerators, in which a tight seal is required to prevent heat entrance to the interior of the refrigerator, causing loss of refrigeration efficiency, therefore, increased expense in the operation of the refrigerating mechanism associated with the refrigerator. In order to have such tight seal, a magnetic closure at all four edges of thedoor is needed, and the magnetic force exerted should be relatively strong in order to maintain the gasket between the door and refrigerator in tightly sealed condition. Therefore to open the door with a breakin of the force of attraction, which is exerted when the door is closed, may be greater than is practical for a direct upward pull on a fixed handle on a refrigerator door.
With our invention, manually operable means are provided for breaking the magnetic seal between the door and the refrigerator casing, first at the outer free edge of the door, and in a manner such that the manual force required is greatly reduced over what is required when a direct pull on a handle on the door is used. Through a novel lever operation which also serves as a handle to open the door, the holding or magnetic force is more easily broken with the exertion of a much less upward pull, so that undue strength is not required in the one opening the refrigerator door.
For an understanding of the invention, and novel mechanisms for accomplishing the objects and results stated, reference may be had to the following description, taken in connection with the accompanying drawings, in which,
Fig. 1 is a front elevation of a refrigerator having our invention, in one form, incorporated therein.
Fig. 2 is a fragmentary enlarged horizontal section substantially on the plane of line 22 of Fig. 1, looking in a downward direction, with the door closed.
Fig. 3 is a similar section illustrating the door in the first steps of being opened, and the initial breaking of the magnetic force holding the door closed.
Fig. 4 is a fragmentar vertical section substantially on the plane of line 3-4 of Fig. 2.
Fig. 5 is a fragmentary horizontal section similar to Fig. 2, taken on the plane of line 5--5 of Fig. 7, illustrating a structure for opening the door which is a modification of and has lesser parts in use than that shown in Figs. 2 and 3.
Fig. 6 is a section similar to Fig. 3, showing the door and release mechanism of Figs. 5 and '7 in the initial step of being opened, Fig. 5 showing it in closed position.
Fig. 7 is a fragmentary edge elevation and partial vertical section substantially on the line 'l1 of Fig. 6.
Fig/8 is a fragmentary horizontal section similar to Fig. 2, showing a still further modified form of means incorporating the invention with the door closed, and
Fig. 9 is a like view, with the door in the act of being opened.
Like reference characters refer to like parts in the different figures of the drawings.
The refrigerator casing or housing I and the door 2 for closing its front opening, hinged adjacent one vertical edge on the casing, are of conventional structure. At the inner side of the door 2, and entirely around it adjacent its edges, a compressible gasket is permanently secured. The gasket which is hollow lengthwise, has a base 3 fastened to the door, an outer side 4 extending therefrom, a longer inner side 5 spaced from the side 4, and an integral connection between the inner edges of the sides t and 5, integral with which is a generally channel-like, inside located, retainer 6 for a plurality of magnets I which are disposed in end to end contact relation to each other (Fig. 4) lengthwise of the gasket. This makes a compressible gasket which when the door is closed has the base 3 and the opposite side of the gasket parallel to each other, as in Fig, 2. This causes the slightly longer side 5 to take a bowed or convex form. The magnets 1, as shown in cross section in Figs. 2 and 3, preferably, are of a shallow U or horseshoe shape the opposed poles of the magnets extending lengthwise thereof.
The gasket may be extruded from suitable rubber composition in any lengths desired. Also integrally formed with the gasket in parallelism with the magnet retainer 6, and at the inner side thereof, is a longitudinal rib in which an elongated bar 8 is embodied. A rod 9 is pinned or otherwise connected with the rod 8 and extends outwardly through the door 2 at a point between the upper and lower ends of the door. The rod is normally moved inwardly by a coiled compression spring Ii! around the rod, between a collar H thereon and the outer side of the door. A handle I? has a pivotal connection at 13 to the 3 outer end of the rod 9. The handle is also pivotally connected at M on a holding fixture I5 therefore secured at the outer side of the door.
The handle 12, as shown in Fig. '7, is a simple lever of the second class. On pulling outwardly on the handle I2, rod 9 is pulled lengthwise outwardly and the spring It compressed, thereby drawing'the bar 3 from the position in Fig. 2 to that in Fig. 3, with a consequent greater bowing or distortion of the side 5 of the gasket. And the poles of the magnets l farthest away from the edge of the door are first moved away from the adjacent face of the refrigerator casing l, as shown in Fig. 3.
A short rod it, normally having its inner end in proximity to such outer face of the refrigerator casing i that the gasket bears against, extends through the inner side of the door 2 and has a pivotal connection within the body of the door to one end of a lever 11, which is pivotally mounted between its ends ona bracket is secured within the body of the door '2. The other end of the lever H has pivotal connection to the rod 9. Thus, when the rod 5 is pulled outwardly, the rod it is simultaneously moved inwardly. On such inward movement its free end presses against the outer face of the refrigerator casing l and helps to separate the gasket, at its outer edge portions from the adjacent face of the casing l.
The structure in Figs. 5, 6 and 7 is the same as that in Figs. 1 to 4 inclusive, except that the rod it, lever i! and bracket 18 are not used. Therefore, the separation of the gasket from the refrigerator through the manualv operation of the handle or lever 12 is solely by pulling the bar 8 outwardly first separating one of the poles of the magnets l and then, on further outward movement or the door, separating the entire gasket so that the door may be opened.
It is apparent that when the door is closed the force of attraction of the magnets upon the steel material at the face of the refrigerator casing around the door, will maintain the door in a tight sealed relation to the refrigerator casing. Such door, if attempted to be opened by a direct pull upon'a handle fixedly secured on the outer side of the door, requires the exertion of a force sufficient to substantially break the magnetic force of all of the magnets, at least in the gasket at the outer free edge of the door, simultaneously followed thereafter by a rapidly succeeding breaking of the force of the magnets in the gaskets at the upper and lower edges of the door and, finally, of those at the inner or hinged edge of the door. The leverage provided by the handle 12, as a lever of the second class, not only multiplies the effective force manually applied to the lever, because of the much longer arm to which the manual force is applied, but also more readily breaks the magnetic seal between the door and casing because the magnets are not pulled directly outward substantially in a line at right angles to the plane of the face of the door. But they are first detached along the inner pole of each magnet and afterward at the remaining outer poles thereby materially reducing the force necessary to release the magnets entirely from the attraction of the casing.
In Figs. 8 and 9 the invention is embodied in a modified structure, the operation of which is the reverse of that previously described.
The rod so, similar to the rod 9, is positioned farther inward and is not connected with the gasket but, when the door is closed, its inner end bears against a plate !9 when the lever or handle (2a, pivotally mounted upon the fixture I5 is manually operated. The handle lZa is mounted as a simple lever of the first class. Upon outward pull thereon it moves the rod 9a inwardly, instead of such rod being drawn outwardly as in the previously described structures. When the door is closed the gasket side 5 is bowed into convex form to a greater degree than in the previous structures. Thus when the door is opened by pulling outwardly on the handle {2a, the shorter side 4 of the gasket will be first drawn away from the face of the refrigerator casing i, before the inner side of the gasket straightening out from the position shown in Fig. 8 to that shown in Fig- 9, i. e., the gasket is peeled away from the casing in such manner that a greatly reduced force is necessary fully to break the seal.
Thus one of the poles of the magnets will first bepulled away from the face of the refrigerator casing before the opposite poles of such magnets, and the resultant lessening of force required to open the door will be substantially the same in degree. The spring iii likewise is reversed in position and in its action, so as to normally tend to return the handle 12a to a position substantially parallel to the outer side of the door 2 when it is released, after having been pulled upon to open the door.
By reason of the structures described, the magnetic closure or the refrigerator door, wherein sealing the door is of greater importance than with many other doors, is effectively accomplished, with the necessary magnetic force furnished so that the door sealing to a required degree is obtained; yet at the same time, the door may be readily and easily opened without the necessity of undue manual force being exerted.
The invention is defined in the appended claims and is to be considered comprehensive of all forms of structure coming within their scope.
We claim:
