Description
~ Z~ 6D-5233 " , This invention relates to an electric oven toaster, and more particularly, to a simplified linking mechanism between an oven toaster door and a switch for closing the switch when the door is closed and opening the switch when the door is opened.
In a prior United States Patent No. 3,684,861 dated August 15, 1972 to Harold A. DeRemer, assigned to the same assignee as the present invention, there is disclosed an arrangement for controlling operation of an oven toaster.
With particular reference to FIG. 1, a push-button 60 may be moved upwardly from an OFF position to an OVEN position, or downwardly from the OFF position to a TOAST position.
A main switch 40 is provided for controlling energization of heating elements 22, 23, 24 and 25, and a linking mechanism 3, 72 - 80 is provided between a door 16 and the main switch 40. With the push-button 60 in either the TOAST position or the OVEN position the linking mechanism 3, 72 - 80 functions to close the main switch when the door is closed and open the main switch 40 when the door is opened.
The push-button 60 is directly connected to lever 154, and as shown more particularly in FIG. 4, operation of the lever 154 moves cam 162 and levers 71 and 74 to actuate the switch 40. With reference to FIGS. 1, 16 and 4, the door 16 is connected to a movable carriage 3 that has a roller 70 mounted thereon so that when the carriage has been moved rearwardly to the position illustrated in FIG. 4 the roller 70 abuts an end 72 of the lever 74 to move lever 80 to the switch closed position. When the door 16 is opened, the carriage 3 is moved forwardly to move the roller 70 to the position illustrated in FIG. 5 to open the switch contacts.
My invention is concerned with such an oven toaster control rnechanism, and more particularly, to an improved ~ 6D-5233 simplified linking mechanism between an oven toaster door and an oven toaster main switch for moving the main switch to a closed position whenever the door is closed and open-ing the switch whenever the door is opened.
Accordingly, it is a particular object of my invention to provide an improved simplified linking mechanism between an oven toaster door and an oven toaster main switch having relatively few parts which may be readily manufactured and assembled to each other.
It is a further object of this invention to provide a rugged and reliable linking mechanism between an oven toaster door and an oven toaster main switch which may be readily operated over and over again without breaking or becoming ineffective.
In accordance with one of the aspects of this invention an electric oven toaster includes a front door for opening and closing an enlarged opening in a front wall, a heating means for supplying heat to a toasting chamber, and a switch for energizing and de-energizing the heating means. A
single link is positioned between the front door and the switch for opening the switch when the door is opened and closing the switch when the door is closed. One end portion of the door link is inserted through an aperture that is provided on the door and the other end portion of the door link is conveniently inserted in an aperture that is provided in a switch actuating member. A spring is connected to the door link and to a rear wall of the oven toaster for biasing the switch to a switch closed position and the door to a door closed position. Thus, when the door is opened the door link and the switch actuating member are moved for-wardly asgainst the force of the spring to open the switch, and when the door is closed the spring assists in urging .
~ 6D-5233 - the door and the switch to a closed position and holds -the door and the switch in their closed positions.
Accordingly, with my improved construction arrangement relatively few parts are required for providing a linking mechanism between an oven toaster door and a switch for closing the switch when the door is closed and opening the switch the door is opened. A single link is provided between the door and a switch actuating member and a single spring is provided for holding the parts in their closed positions.
The apertures in the door and the switch actuating member are readily formed during the manufacture of the door and the switch. Thus, an exceedingly simple and reliable linking mechanism has been achieved.
Moreover, with this unique construction the parts may be readily assembled to each other. One end of the door link may be readily hooked through the aperture in the door, the other end of the link may be inserted through the aperture in the door, the other end of the link may be inserted through the aperture within the switch actuating - -~
member, and the single spring may be readily hooked over the door link and the rear wall of the oven toaster. Accordingly, the parts may be readily and easily assembled to each other.

With particular reference to FIG. 1, a push-button 60 may be moved upwardly from an OFF position to an OVEN position, or downwardly from the OFF position to a TOAST position.
A main switch 40 is provided for controlling energization of heating elements 22, 23, 24 and 25, and a linking mechanism 3, 72 - 80 is provided between a door 16 and the main switch 40. With the push-button 60 in either the TOAST position or the OVEN position the linking mechanism 3, 72 - 80 functions to close the main switch when the door is closed and open the main switch 40 when the door is opened.
The push-button 60 is directly connected to lever 154, and as shown more particularly in FIG. 4, operation of the lever 154 moves cam 162 and levers 71 and 74 to actuate the switch 40. With reference to FIGS. 1, 16 and 4, the door 16 is connected to a movable carriage 3 that has a roller 70 mounted thereon so that when the carriage has been moved rearwardly to the position illustrated in FIG. 4 the roller 70 abuts an end 72 of the lever 74 to move lever 80 to the switch closed position. When the door 16 is opened, the carriage 3 is moved forwardly to move the roller 70 to the position illustrated in FIG. 5 to open the switch contacts.

A single link is provided between the door and a switch actuating member and a single spring is provided for holding the parts in their closed positions.
The apertures in the door and the switch actuating member are readily formed during the manufacture of the door and the switch. Thus, an exceedingly simple and reliable linking mechanism has been achieved.
Moreover, with this unique construction the parts may be readily assembled to each other. One end of the door link may be readily hooked through the aperture in the door, the other end of the link may be inserted through the aperture in the door, the other end of the link may be inserted through the aperture within the switch actuating - -~

Other objects and attendant advantages of the invention will be apparent from the following description taken in connection with the accompanying drawing in which:
FIG. 1 is a perspective view of an electric oven toaster embodying my improved door linking mechanism;
-) FIG. 2 is a fragmentary ee~-sectional view of a portion of the oven toaster taken substantially on the plane of
2-2 of FIG. 1 illustrating the positions of the parts after the door and the switch have been closed;
FIG. 3 is cross-sectional view of the oven toaster ~ 6D~5233 similar to FIG. 2 showing the positions of the parts after the door and the switch have been opened; and FIG. 4 is a perspective view of my unique door link rod and spring.
Referring now to the drawing and first particularly to FIGS. 1 and 2 there is shown an electric oven toaster which includes a toasting and oven chamber 2 in which is mounted a generally horizontal rack 4 for holding food to be cooked or bread to be toasted. The oven toaster includes a generally vertical front wall 6, a generally horizontal top wall 8, generally parallel vertical side walls 10 and 12, a bottom wall 14 and a rear wall 16.
An enlarged front opening 20 is provided in the front wall of the oven toaster to provide access to the inside of the toaster, and a front door 22 is provided for closing the front opening. The door is pivotally mounted at 24 to the lower portion of the oven toaster, and as shown in FIG.
1, a handle 26 is provided for opening the door.
The electric oven toaster includes a main switch 30 for energizing heating elements 32 and 34 and other heating elements not shown. ~s illustrated in FIGS. 3 and 4, the toaster main switch 30 is located at a lower rear portion of the oven toaster, and includes a fixed contact or contacts 36 and a movable contact or contacts 38. While the details of the switch 30 do not form a part of my invention, and are described and illustrated in greater detail in my prior U.S. Patent No. 3,529,534 dated September 22, 1970 to Reznik et al, assigned to the same assignee as the present invention, a brief description of the switch is desirable for an understanding of the instant invention.
It should be appreciated that the housing of switch 30 is formed from phenolic plastic or other suitable insulating material, ,.,~., .,~,.
~ - 4 -~3~6~ 6D-5233 and an actuating cam lever 40 is integrally formed with a shaft member 42 which is mounted for rotation within recesses that are formed in the plastic switch housing. Thus, when the shaft member 42 is rotated from the position illustrated in FIG. 2 to the position illustrated in FIG. 3 the cam member 40 acts against the upper switch blade 44 to move the switch blade upwardly to open the switch contacts 36 and 38.
The overall toaster control mechanism of the oven -toaster illustrated in FIG. 1 does not form a part of this invention and is described and illustrated in greater detail in my Canadian Patent No. 1,111,472 dated October 27, 1981, assigned to the same assignee as the present invention.
In accordance with my invention a switch actuating lever 50 is integrally molded with the switch actuating cam 40 and shaft 42. As shown in FIGS. 2 and 3, the actuating lever 50 extends radially from the shaft 42 at an acute angle with respect to the cam 40. An aperture 52 is formed in the upper end portion of the actuating lever 50 for receiving my unique door link rod 60.
With particular reference to FIGS. 4, 2 and 3 it can be appreciated that my unique link rod 60 may be readily shaped from a piece of wire. As shown, the link wire rod 60 may be positioned generally horizontally within the oven toaster and shaped to have suitable clearance between other portions of the oven toaster. For example, the central portion 62 may include an upwardly extending bend 64 for spacing the link 60 from a mounting tab 66. A rearward portion 68 of the rod extends in a generally transverse direction with respect to the central portion 62 of the rod for convenient insertion within the aperture 52 that is formed ~,, ~2~ 6~-5233 in the switch actuating lever 50. The forward portion 70 of the rod link may extend transversely to the left for in-sertion within an aperture 72 that may be formed in a conveniently positioned door tab 74. The forward portion 70 of the link may also include an upwardly extending portion 76 for positively hooking the link to the door tab 74.
With particular reference to FIG. 2, it can be appre-ciated that a readly available coil spring 80 having two hooked end portions 8~ and 84 may be utilized for holding the door and the switch in their closed positions. End portion 84 may be simply hooked through an aperture in a tab 86 that is provided in the rear wall 16 of the oven toaster, while the forward hooked portion 82 may be placed over the transverse end portion 68 of the door link in order to urge the parts in the position illustrated in FIG. 2.
With this unique construction it can be appreciated that the parts may be easily assembled to each other in a very simple manufacturing operation. The forward end 76 -70 of the link may be simply inserted through the aperture 72 in the door tab 74 and turned so that end 76 extends upwardly. Then the transverse rear portion 68 of the link may be inserted through the aperture 52 that is formed in the switch actuating lever 50. The assembly is completed by simply hooking the spring 80 to the rear wall of the oven toaster and the transverse portion 68 of the link.
In operation when the door is opened from the posi-tion illustrated in FIG. 2 to the position illustrated in FIG. 3 the door pivots about pivot 24 and the door tab 74 is moved forwardly from the position illustrat~d in E'IG.2 to the position illustrated in FIG. 3. During this opera-tion, the link rod 60 is also moved forwardly against the ;L1~1 force of spring 80, and the switch actuating lever 50 i5 moved forwardly and counterclockwise to rotate the shaft 42 and the cam member 40 from the position illustrated in FIG. 2 to the position illustrated in FIG. 3 to open the switch contacts. When the door is closed, the spring 80 assists in closing the door and closing the switch con-tacts 36 and 38 and holds the door in the closed position illustrated in FIG. 2.
From the foregoing description it will be appreciated that my improved simplified switch and door linking mecha- -nism has been achieved with relatively few parts. A single easily formed wire rod 60 is positioned between a switch operating lever 50 and a door tab 74. A readily available coil spring 80 is provided for urging the switch and the door to their closed positions. Thus, an exceedingly simple and reliable mechanism is achieved with the use of relatively few parts.

FIG. 3 is cross-sectional view of the oven toaster ~ 6D~5233 similar to FIG. 2 showing the positions of the parts after the door and the switch have been opened; and FIG. 4 is a perspective view of my unique door link rod and spring.
Referring now to the drawing and first particularly to FIGS. 1 and 2 there is shown an electric oven toaster which includes a toasting and oven chamber 2 in which is mounted a generally horizontal rack 4 for holding food to be cooked or bread to be toasted. The oven toaster includes a generally vertical front wall 6, a generally horizontal top wall 8, generally parallel vertical side walls 10 and 12, a bottom wall 14 and a rear wall 16.
An enlarged front opening 20 is provided in the front wall of the oven toaster to provide access to the inside of the toaster, and a front door 22 is provided for closing the front opening. The door is pivotally mounted at 24 to the lower portion of the oven toaster, and as shown in FIG.
1, a handle 26 is provided for opening the door.
The electric oven toaster includes a main switch 30 for energizing heating elements 32 and 34 and other heating elements not shown. ~s illustrated in FIGS. 3 and 4, the toaster main switch 30 is located at a lower rear portion of the oven toaster, and includes a fixed contact or contacts 36 and a movable contact or contacts 38. While the details of the switch 30 do not form a part of my invention, and are described and illustrated in greater detail in my prior U.S. Patent No. 3,529,534 dated September 22, 1970 to Reznik et al, assigned to the same assignee as the present invention, a brief description of the switch is desirable for an understanding of the instant invention.
It should be appreciated that the housing of switch 30 is formed from phenolic plastic or other suitable insulating material, ,.,~., .,~,.
~ - 4 -~3~6~ 6D-5233 and an actuating cam lever 40 is integrally formed with a shaft member 42 which is mounted for rotation within recesses that are formed in the plastic switch housing. Thus, when the shaft member 42 is rotated from the position illustrated in FIG. 2 to the position illustrated in FIG. 3 the cam member 40 acts against the upper switch blade 44 to move the switch blade upwardly to open the switch contacts 36 and 38.
The overall toaster control mechanism of the oven -toaster illustrated in FIG. 1 does not form a part of this invention and is described and illustrated in greater detail in my Canadian Patent No. 1,111,472 dated October 27, 1981, assigned to the same assignee as the present invention.
In accordance with my invention a switch actuating lever 50 is integrally molded with the switch actuating cam 40 and shaft 42. As shown in FIGS. 2 and 3, the actuating lever 50 extends radially from the shaft 42 at an acute angle with respect to the cam 40. An aperture 52 is formed in the upper end portion of the actuating lever 50 for receiving my unique door link rod 60.
With particular reference to FIGS. 4, 2 and 3 it can be appreciated that my unique link rod 60 may be readily shaped from a piece of wire. As shown, the link wire rod 60 may be positioned generally horizontally within the oven toaster and shaped to have suitable clearance between other portions of the oven toaster. For example, the central portion 62 may include an upwardly extending bend 64 for spacing the link 60 from a mounting tab 66. A rearward portion 68 of the rod extends in a generally transverse direction with respect to the central portion 62 of the rod for convenient insertion within the aperture 52 that is formed ~,, ~2~ 6~-5233 in the switch actuating lever 50. The forward portion 70 of the rod link may extend transversely to the left for in-sertion within an aperture 72 that may be formed in a conveniently positioned door tab 74. The forward portion 70 of the link may also include an upwardly extending portion 76 for positively hooking the link to the door tab 74.
With particular reference to FIG. 2, it can be appre-ciated that a readly available coil spring 80 having two hooked end portions 8~ and 84 may be utilized for holding the door and the switch in their closed positions. End portion 84 may be simply hooked through an aperture in a tab 86 that is provided in the rear wall 16 of the oven toaster, while the forward hooked portion 82 may be placed over the transverse end portion 68 of the door link in order to urge the parts in the position illustrated in FIG. 2.
With this unique construction it can be appreciated that the parts may be easily assembled to each other in a very simple manufacturing operation. The forward end 76 -70 of the link may be simply inserted through the aperture 72 in the door tab 74 and turned so that end 76 extends upwardly. Then the transverse rear portion 68 of the link may be inserted through the aperture 52 that is formed in the switch actuating lever 50. The assembly is completed by simply hooking the spring 80 to the rear wall of the oven toaster and the transverse portion 68 of the link.
In operation when the door is opened from the posi-tion illustrated in FIG. 2 to the position illustrated in FIG. 3 the door pivots about pivot 24 and the door tab 74 is moved forwardly from the position illustrat~d in E'IG.2 to the position illustrated in FIG. 3. During this opera-tion, the link rod 60 is also moved forwardly against the ;L1~1 force of spring 80, and the switch actuating lever 50 i5 moved forwardly and counterclockwise to rotate the shaft 42 and the cam member 40 from the position illustrated in FIG. 2 to the position illustrated in FIG. 3 to open the switch contacts. When the door is closed, the spring 80 assists in closing the door and closing the switch con-tacts 36 and 38 and holds the door in the closed position illustrated in FIG. 2.
From the foregoing description it will be appreciated that my improved simplified switch and door linking mecha- -nism has been achieved with relatively few parts. A single easily formed wire rod 60 is positioned between a switch operating lever 50 and a door tab 74. A readily available coil spring 80 is provided for urging the switch and the door to their closed positions. Thus, an exceedingly simple and reliable mechanism is achieved with the use of relatively few parts.
