BASE FOR ELECTRICAL HOUSEHOLD APPLIANCES Filed Dec. 1, 1958 0564/? M A/VDE/PSO/V N/LS 7T ALMQU/JT Patented Sept. 12, 1939 UNITED STATES PATENT OFFICE BASE FOR ELECTRICAL HOUSEHOLD APPLIANCES Connecticut Application December 1, 1938, Serial No. 243,391
The present invention relates to a base for electrical household appliances such as toasters, waflle irons, or portable ovens and the like, and more particularly to improved feet or legs for 5 the base.
The present invention aims to provide an improved base for appliances of the above type having feet which can be manufactured inexpensively, are attractive in appearance, sturdy in construction and can be readily attached to the base.
Other objects will be in part obvious, and in part pointed out more in detail hereinafter.
The invention accordingly consists in the features of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application of which will be indicated in the appended claims.
In the accompanying drawing:
Figure 1 is a perspective view of a toaster, illustrating an embodiment of the present invention;
Fig. 2 is an enlarged fragmentary perspective view, illustrating in detail one of the feet or legs shown in Fig. 1;
Fig. 3 is a fragmentary perspective View taken from the inside of the base, illustrating a foot attached to the base;
Fig. 4 is a perspective view, similar to Fig. 3, illustrating a foot prior to being attached to the base;
Fig. 5 is a side elevational View illustrating a foot and the parts for attaching it to the base;
Fig. 6 is a sectional view of a foot and a corner of the base and the parts for attaching the foot to the base; and
Fig. 7 is a sectional view, similar to Fig. 6, illustrating the foot secured to the base.
Referring more particularly to the drawing, there is shown in Fig. 1 an electrical household appliance, which for illustrative purposes may be a toaster, comprising a body part In, a base H, and feet or legs l2 secured to the base.
Preferably, the base is rectangular in shape and has a substantially horizontal upper surface M for mounting the body part It, and a downwardly depending skirt or flange l5. At the corners of the flange, suitable cutaway portions, openings or recesses l6 (Fig. 6) are provided for receiving the feet l2, as about to be described. The edge portions I! of the flange defining the openings are substantially vertical (Figs. 3 and 4) and are provided with a suitable tab l8 bent inwardly at right angles with respect to the flange (Figs. 6 and 7). The mounting surface of the base preferably is rounded at the corners [9 thereof to improve its appearance and-eliminate sharp edges and the underside of the corners is adapted to abut the upper surface of the feet.
The feet preferably are substantially triangular in cross section and comprise adjacent sides 20 and 2| disposed at right angles to each other and a side 22 diagonally disposed to the sides 20 and 2| at an angle of approximately forty-five degrees. The upper surface 23 of the feet is flat and horizontal and is adapted to fit against and lie parallel with respect to the underside of the corners IQ of the base. The lower surface of the feet preferably is also flat and horizontal to provide a firm support for the base.
The diagonal side 22 is adapted to abut the corners of the flange and has substantially vertical grooves 24 for receiving the vertical edges l1 thereof. The grooves 24 preferably comprise a pair of right angularly related faces 25 and 26, with the face 25 adapted to abut the free edge of the flange and the face 26 adapted to lie against the outer surface of the flange of the base in substantially parallel relation thereto.
Intermediate the top and bottom and substantially at the mid-point, each of the grooves 24 is increased in depth to provide a recess 21 for receiving the tabs 18. The recess has a face 28 disposed at right angles to the face 26 of the groove, serving as an abutment for the tabs I8 and has upper and lower faces 29 and 30 adapted to engage the respective upper and lower edges of the tab portions to align the feet with respect to the flange and prevent relative vertical movement therebetween. The side 22 of the foot has a threaded aperture 3| located intermediate and in horizontal alignment with the recesses for receiving a screw for connecting the foot to the flange, as about to be described.
The feet are adapted to be secured to the base by a strip or bar 35, preferably having an outwardly projecting ear 36 at each end thereof, bent at right angles with respect to the strip and adapted to engage the tabs I8 of the flanges of the base. The strips are attached to the feet by a suitable screw or bolt 3'! extending through an aperture 39 in the strip and threaded into the aperture 3 I. When the screw is threaded into the foot, the head 40 thereof urges the strip towards the foot and causes the ears 36 to engage the tabs to securely hold the tabs in the recesses. If desired, the strips may be formed of slightly bendable metal so that upon securing of the screw they bear resiliently against the head and serve in effect as a lock washer for preventing accidental unscrewing of the screw.
It will be seen that the present invention provides an improved base for electrical household appliances which is readily made and provided with suitable supporting feet. The vertical grooves in the feet cooperate; with the vertical edges of the flange of the base to hold the feet in vertical alignment, while the recesses in the 20 construction and many apparently widely different. embodiments of thisinvention could bemade. without. departingv from the scope thereof,
it. islintended that all matter contained in the above description. or shown in the accompanying 25 drawing shall be. interpreted aslillustrative and not in. a limiting. sense.
It. is. also to be understood that the language used in the following claims is intended to cover all of .the generic andspecific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
Havingthus. described our invention we claim:
