1. Technical Field of Invention
The embodiments herein generally relate to electric toasters, and particularly to “pop-up” toasters. The embodiments herein more particularly relate to pop-up toasters wherein a bread is raised above the toaster after toasting and ejects completely and falls off at a predetermined distance from the toaster.
2. Description of Related Art
Electric toasters, or so-called “pop-up toasters” are well known household appliances which are used on a regular basis for toasting a variety of bread products. Such toasters are normally equipped with electromechanical means that act to raise a slice of toasted bread and switch off the toaster once a toasting operation has been completed.
In general, bread slices or other articles to be toasted are inserted vertically into slots at the top of the toaster, into a bread support comprising side guides, for holding a slice of bread upright, and a moveable supporting base, which is movable by a lever, on one side of the toaster, for raising and lowering the bread between the guides. The guides are surrounded by heating elements for heating both sides of the bread simultaneously.
Once the toasting operation is completed, a timer or other sensing device is used to automatically turn off electrical power to the heating elements. At the same time the lever is moved to lift the bread support and thereby lift the toast above the height of the toaster so that it may be manually removed for consumption.
If the bread is too small, then even after ejection, or “popping” of the bread support, it is difficult to access the toasted bread as it does not project above the height of the toaster. Also, as the bread is not totally ejected at the end of the toasting operation, there is a risk that a fire could be caused, for example, if the electrical supply to the heating elements is not switched off; the heating elements continue to heat and then char and possibly ignite the bread with the production of a flame, which could spread to flammable material in the proximity of the toaster.
Hence there is a need to develop a toaster which alleviates the above mentioned problems and also give advantages of automatically and timely ejection of the toast and falling off from the toaster slots to a predetermined distance away from the toaster.
The above mentioned shortcomings, disadvantages and problems are addressed herein, as detailed below.
The primary object of the embodiments herein is to provide an electric toaster wherein the base portion is raised and tilted up to a certain extend enabling the toast to eject out completely and fall off at a predetermined distance from the toaster body.
Another object of the embodiments herein is to provide an electric toaster that automatically cuts off the current after the bread is toasted.
Yet another object of the embodiments herein is to provide an electric toaster having a stronger spring that enables a toast to fall off at a predetermined distance from the toaster bread following a projectile path.
Yet another object of the embodiments herein is to provide an electric toaster enabling an equal toasting of bread from all directions.

According to a preferred embodiment of the invention, and with respect to
The toaster body 3 has a rectangular base 11 with a rear wall 13, front wall 15 and two side walls 17 extending upwardly therefrom towards a top surface 19. The top surface 19 is provided with two slots 21 along the length thereof for receiving a bread product to be toasted.
The rectangular base 11 of the toaster body 3 is provided with two rear feet 23, located below the rear wall 13 and two front feet 25 located below the front wall 15. The rear feet 23 are longer than the front feet 25, resulting in the toaster body 3 being tilted from its vertical plane or horizontal plane from the base. Due to this tilted set up, the bread supporting assembly 5 within the toaster body is also tilted from the vertical plane; and as a result causes the trajectory of a toasted bread product being ejected from the toaster body 3 to be in a vertical and transverse direction and towards the front side of the toaster, on the side of the front wall 15.
A removable crumb tray 27 is positioned below the toaster body 3 to collect falling crumbs from toasting bread product.
The bread supporting assembly 5 is an open framework wire structure with side guides, for supporting a bread product, and the moveable base member 7 which is slidably moveable between the guides from a lower retracted toasting condition, for operatively positioning the bread product between the heating elements 9, to a raised ejecting condition, for operatively ejecting a toasted bread product out of the slot 21. The open spaces between the side guides of the bread supporting assembly 5 allow exposure of a bread product placed therein to the surrounding heating elements 9, when the base member 7 is moved to its lower retracted toasting condition.
The heating elements 9 consist of mica sheets 29 with heating wires 31 wrapped helically around the mica sheets, with their convolutions spaced from each other. The mica sheets 29 are positioned within the toaster body 3 such that they are on either side of the bread supporting assembly 5. The heating elements 9 are positioned closer to the one side of the bread supporting assembly (in this embodiment, the top side, closer to the rear wall 13) than the other (on the side of the front wall 15), so that the bread receives an even toasting even though it is resting at a tilted angle on the one side of the assembly. The heating elements 9 operate in the conventional manner, used in well-known toasters available in the market place.
The ejector means 40 located in the toaster body 3 below the base member 7 comprise a timing lever 42 and a trip lever 44. The timing lever 42 is moveable up and down in a first vertical slot 46 in the rear wall 13 of the toaster body 3 and the trip lever 44 is moveable in a second vertical slot 48 in the rear wall of the toaster body.
The timing lever 42 is connected to a timing device 80 which, in this embodiment, includes a clockwork mechanism mounted in a box. The clock mechanism is of any standard construction known in the art. A cylindrical member 82 of the clock mechanism is secured to one end of a chain 84 and the other end of the chain is secured to the timing lever 42 pivoted at its rear end near the front wall 15 to a rod 54. Depression of the timing lever 42, pulls the chain 84 to wind up a spring of the clock mechanism in the timing device 80.
An adjustable stop arm 68 is provided towards the base 11 of the toaster body 3, for stopping the movement of the timing arm 42. The opposite end of the stop arm 68 is pivoted 62 and is secured to an upwardly extending arm 74. The stop arm 68 and upwardly extending arm 74 are secured by a brace arm 72. The pivot 62 is mounted to a vertical slot 64 formed in a member 66 extending from the base 11 of the toaster body 3. The pivot 62 is urged into a downward position in this slot 64 by a coiled spring 70 attached at its upper end to the upwardly extending arm 74 and attached to the member 66 at its lower end. The upper end of the upwardly extending arm 74 terminates in a handle portion 90 which carries a detent 92 adapted to be engaged in any one of a number of notches formed in the upper edge of an angular member 94 secured on the top surface 19 of the toaster body 3. The horizontal portion of the angular member 94 bears numbers corresponding to different notches. On lifting the handle portion 90, the detent 92 is moved from its notch, whereupon the handle portion 90 may be moved towards the right or left and the detent 92 and may then be engaged in any desired notch. As the handle is moved towards the right, as viewed in
The trip lever 44 is also pivoted at its rear end near the front wall 15 on the rod 54 at which place it is provided with a downwardly extending arm 86. The downwardly extending arm 86 is connected by a coiled spring 88 to the rear wall 13 of the toaster body 3 so that the trip lever 44 is normally spring loaded into an upward position. The trip lever 44 is connected to the moveable base member 7, and manually moves the base member 7 down to its retracted condition when the trip lever 44 is depressed, or raises the base member 7 upwardly to its ejecting condition when the trip lever 44 is pulled up by the coiled spring 88.
When the trip lever 44 is pulled down as far as it goes against the tension of the spring 88, it is engaged by a triangular shaped gravity catch device 90. The catch device 90 has three members, forming an upper member 92, side member 93 and lateral member 96 of a triangle, and is pivoted 98 to the toaster body 3 towards the side wall 17, so as to normally swing towards the left, as viewed in
In use, slices of bread are placed in the bread supporting assembly 5, through the slots 21 at the top of the toaster body 3, and lie between the side guides of the bread supporting assembly 5, and on the base member 7. The trip lever 44 is depressed to its retracted condition to lower the bread into the toaster body and between the heating elements 9. The timing lever 42 is depressed at the same time or just prior to the depression of the trip lever 44.
When the trip lever 44 is depressed, an electrical power switch arranged to supply power to the heating elements 9 is closed and the heating elements begin toasting the bread product.
The timing lever 42, when depressed, pulls the chain 84 and winds up the spring of the clock mechanism of the timing device 80. The timing lever 42 is moved down until its strikes one end of the adjustable stop arm 68. As the chain 84 is wound up, the timing lever moves upwardly until strikes the bottom of the upper member 92 of the triangular catch device 60. Lifting of the upper member 92 causes the catch device 90 to pivot to the right, as viewed in
According to the embodiments herein, the toast after the toasting is completed rises not only to the surface of the toaster but also completely gets ejected out of the toaster onto a counter or plate placed at a predetermined distance of at least 3 cm. The entire toaster including all the working mechanisms within the toaster are set at an angle enabling the toasted bread to land on the counter/plate beside the toaster.
According to an embodiment herein, the angle is below 90 degrees, preferable the angle is below 90 degrees large enough to give sufficient tilt to cause adequate ejection of the toasted bread. The angle is preferably between 10 degrees to 75 degrees.
The electric toaster of the present invention is aimed at an oblique movement of the toasted bread and enabling the toast to be ejected onto a counter or plate placed beside the toaster body.
According to an embodiment herein, a resting grid supporting the lower side of the leaning bread is placed slightly further from the lower heating elements in both slots allowing the bread to be situated equidistant from the two heating elements thus enabling the bread to be toasted evenly dark on both sides.
