Claims. (Cl. 220-45) This invention relates to household appliances and more particularly to a novel means for .hinging an access door to household appliances such as laundry machines, ovens, and the like.
As is Well known, it is common practice in the appliance industry to apply hard finishes to the outer surface of the appliance. This finish frequently takes the form of porcelain enamel or the like. inherently, such materials have very little elasticity and tend to chip.
The various household appliances are usually housed in a sheet metal structure, and because of the hard character of the finish, the industry has been constantly plagued with the tendency tor a coating of porcelain enamel or the like, applied to a sheet metal structure to chip, check or cleave whenever localized stresses are developed the sheet metal.
The chipping problem has been particularly bothersome in connection with mounting access doors to appliances wherein it is'necessary to rivet, or screw hinges to the appliance casing. In mounting the hinges to the casing in the above manner, localized stresses are developed in the casing immediately surrounding the heads of the screws or rivets with the result that after varying intervals or time, checks or chips occur in the casing finish.
it is a particular object of the present invention to provide a means for amounting the access door of a laundry appliance which precludes the use of screws and nuts or rivets. s
Another object of the present invention is the provi sion of a counterbalanced access door tor a laundry machine.
Another object of the present invention is the provision of an access door for a laundry machine having a hinge mechanism which operates to center the door automatically with respect to the access opening.
A still further object of the present invention is the provision of a novel means for mounting the access door toa hinge.
7 Another object of the present invention is the provision of simple yet novel hinge structurewhich lends itself to quick removal or replacement-of the access door.
A still further object of the present invention is the provision of a hinged access door provided with resilient bumpers so as to preclude damage to the casing of an appliance, the door, or the hinges.-
A further object of the present invention is the'provision of an access door structure tor ahousehold appliance which may be readily cleaned.
A further object of the present invention is the provisionof a hinge mounting which does not develop localized stress in the supporting structure but which distributes the hinge .loadover a wide area.
A hinged access door embodying the principles of the present invention may comprise a pair of brackets spotwelded to the underside of a household appliance casing,
a pintle pin supported in each bracket, arms rota tably mounted upon the pintle pins and movable along the longitudinal axis of the pins, an access door, said access door 2,826,327 Patented Mar. 11,
having tracks formed therein for accepting the arms, and spring means for urging the arm into engagement with the tracks of the access door.
Other features and advantages of the present invention will become more apparent when considered in coniunction with the appended specification and drawings wherein:
Figure l is a plan view of the upper portion of .a laundry machine with which the present invention may be associated;
Fig. 2 is a sectional view of a portion ofFig. las viewed in the plane of line 2-4;
Fig. 3 is a sectional view of a portion of Fig. 1 as viewed in the plane of line 3-3;
Fig. 4 is a view of the right side of Fig. 3 as viewed in the plane of the line 4-4 and showing theaccess door in the open position;
Fig. 5 is a view similar to the showing of Fig. 4, with the access door in the closed position; and
Fig. 6 is a sectional view of a portion of Fig. 3 as viewed in the plane of line 6-6.
Referring now to Fig. 1, there is shown a laundry ma chine indicated generally by the letter A, having a casing B, formed with an access opening C. The margin surrounding the access opening C is recessed with respect to the plane of the top surface of the casing B, to accommodate an access door D.
Since the present invention is not directed to the specific construction of the laundry machine shown, but may in fact be associated with any household appliance, it is not deemed necessary to describe the laundry apparatus in detail except as is necessary to show the adaptation of the present invention thereto.
In an exemplary embodiment of the present invention illustrated in Fig. 1, the access door D is shown receiving two hinges 10. The hinges 10 engage pockets or tracks 11 formed in the underside of the access door D, in a manner which Will become more apparent as the specification proceeds. A body portion of the hinges 10,, is adapted to engage hinge or pintle pins secured to the under side of the casing B. The hinges are biased by springs 26 shown in dotted lines, and are effective to maintain the access door in an open position. The tension of the springs is so adjusted that upon manually moving the door through a predetermined arc toward a closed position, the force of gravity exerted upon the door, by virtue of its mass, is sufiicient to carry the door to a closed position.
Having shown a particular application of the present invention, and having established an environment therefor, a detailed description thereof will now be undertaken. Referring to Fig. 3, there is shown a top wall 16, of a laundry machine casing whose underside supports a bracket 17. The bracket is spot-welded to the Wall 16, and is formed with two depending cars 18, each having through apertures 19 formed therein for accepting a hinge or pintle pin 21. A body portion 15 of the hinge 10 is rotatably mounted upon the pin 21. The hinge is formed with an L-shaped portion composed of a horizontal arm 13 and a vertical arm 14 adapted to engage the track or pockets 11, formed in the underside of the access .door D. Coil springs 20, mounted on the pins 21, are provided to urge vertical arms 14 into engagement with the track 11 (or to the left as viewed in Fig. 3).
A stop 23 formed in the vertical portion of the track 11 serves to hold the horizontal arm 13 snugly against the horizontal portion of the track 11. a
It is, of course, understood that the hinge of Fig. 3 is one of a pair of hinges and that the second hinge is identical to the hinge of Fig. 3 but of opposite hand.
Referring now to Figs. 1, 2 and 3, it is apparent that the springs 26 engage a cross arm 24 of each hinge as at 27 and are held under tension by a strap or wire 28, encircling :1 depending flange 2g, bounding the access opening C. The function of the springs 26 is to carry the access door D to a full open position after it has been raised through a predetermined angle, such as from a horizontal position, and to partially counterbalance the weight of the door before it has been raised through such an angle.
It is to be understood that the hinges 1%, by virtue of their cooperation with coil springs 2t] and 26, may be urged to and fro along the longitudinal axis of the pins 21, with the result that the access door supported by the hinges will readily center itself with respect to the recess formed in the top panel of the casing.
With the two brackets 17 equally spaced from corresponding sides 3th of the top panel recess, and with the two springs 24) of equal tension, the door will automatically center in the recess.
As is more apparent in Figs. 3 and 4, a projection 32, integral with the cross arm 24 supported by the hinge 10 carries a resilient bumper 33, operable to engage the underside of the marginal areas surrounding the access opening C (as at as) when the door is opened. It is the function of the bumper 33, to absorb shock and preclude the creation of localized stresses that would otherwise develop it the projection 32 were permitted to engage the casing directly.
As is also apparent in Figs. 3 and 4, the horizontal arm 13 of each hinge engages a sidewall 36 of the track 11, while the vertical arm 14 engages a corresponding vertical sidewall 37 of the track. The stop 23 and the wall 36 limit the movement of the door with respect to the hinge in an upward or downward direction as viewed in Figs. 3 and 4. he wall 36 and the stop 23 may be spaced to permit upward and downward motion of the door with respect to the hinge, or the fit may be snug as shown in Fig. 4.
In order to avoid the impracticability of making a snug fit between the L-shaped portion of the hinge 1d, and the track 11, the vertical arm 14 (or the horizontal arm 13) of the hinge is formed with a slot 42 (Pig. 6) for accepting a generally Z-shaped spring 43. A snug fit between the arm 14, the track 11 and thus the door and the hinge, is accomplished by the engagement of the leaves 44, and 46, with the bottom of the slot 42, and the inner side of the door panel 45, respectively. The friction developed between the door D and the spring 43 precludes relative motion between the hinge 10 and the access door.
From the above description of the present invention, it is apparent that the access door D may be readily removed by moving either or both of the hinges it inwardly toward one another against the coil springs 2%. By so doing, the vertical arms 14- are moved out of engagement with the track 11, thus freeing the door. Note that the casing is provided with elongated openings at to permit lateral movement of the hinges.
It is to be noted that the impracticability of maintaining close tolerances necessary to mount the door to the hinges is overcome by the cooperattion of the generally Z-shaped springs 43, the vertical arms 14 and the track 11.
While I have illustrated preferred embodiments of my invention, many modifications may be made without departing from the spirit of the invention, and I do not wish to be limited to the precise details of construction set forth but wish to avail myself of all changes within the scope of the appended claims.
