Ultra low profile rocker design

Abstract

A rocker switch having a housing and a rocker extending from the housing. The rocker has a first side with a first end and a second end, a second side adjacent to the first side, and a channel. The channel is disposed on the second side of the rocker and has a first end and a second end. A pivot point is disposed on a crank. A pin, disposed on the crank, is located in a first side of the channel. The depression of the first end of the rocker causes a rotational movement of the channel in a curvilinear path around the pivot point, causing a rotational movement of the crank, moving the pin from the first end of the channel toward the second end of the channel.

DETAILED DESCRIPTION OF THE INVENTION

(10) The exemplary embodiments of the present invention may be further understood with reference to the following description and the related appended drawings, wherein like elements are provided with the same reference numerals. The exemplary embodiments of the present invention are related to a rocker switch. Specifically, the rocker switch allows for a substantially reduced profile and a substantially reduced depth. The exemplary embodiments are described with reference to single pole rocker switch for use in a circuit breaker, but those skilled in the art will understand that the present invention may be implemented in any rocker switch and is not limited to a single pole switch for use in a circuit breaker.

(11) As best seen in FIGS. 1 and 5, side views of rocker switch 100, in an opened position, are shown. Rocker switch 100 may contain a rocker 105 extending from a housing 140. Housing 140 encloses the entirety of the mechanical and electrical components of rocker switch 100 except for a portion of rocker 105. Rocker 105 may have a substantially curved portion 145 to allow for easier entry into housing 140 when rocker 105 is depressed, however rocker 105 need not have a substantially curved portion 145, and the side of the rocker may be substantially flat depending on the design of the opening in the housing. Opposite curved portion 145 is lip 110. Lip 110 protrudes from rocker 105 to allow for easier activation of rocker 105. Rocker 105 is attached to a pivot point 150, which is located inside of housing 140. Pivot point 150 allows for the rotational movement of rocker 105. When the user swipes his/her finger across rocker 105, to close the rocker, the user is able to grab lip 110 with his/her finger (not shown), facilitating easier operation of rocker 105 to close rocker switch 100.

(12) Rocker 105 includes a channel 120, which is located entirely inside of housing 140. Channel 120 may extend directly from rocker 105 or channel 120 may be a separate component attached to rocker 105. In a preferred embodiment, channel 120 is angled with respect to the top surface of housing 100, and parallel to the angle formed by rocker 105 with respect to housing 100. However, channel 120 may be designed to be parallel with the top surface of housing 100. Channel 120 is shaped as a rectangle with curved ends; however, channel 120 could be of any shape that facilitates pin movement as described below including have one or more open ends. Channel 120 defines an opening sized to be slightly larger than the diameter of pin 115 to allow free movement of pin 115 within channel 120. Pin 115 is attached to crank 125, and is sized to fit within the opening defined by channel 120. When rocker switch 100 is in the open position, with rocker 105 not being depressed, pin 115 is located toward a first end of channel 120.

(13) Rocker 105 is operated by depressing the extended portion of rocker 105. In the exemplary embodiment, the extended portion of the rocker is on the same side of the rocker as pin 115; however, rocker 105 could be designed such that the extended portion is on the opposite side as that of pin 115. It should be noted, that prior art systems require the extended portion to be opposite of the pin so as to cause a lateral movement. The design of the present invention, explained in detail below, allows the extended portion to be on either side of rocker 105.

(14) As best seen in FIGS. 2 and 6, side views of rocker switch 100, in a closed position, are shown. When rocker 105 is depressed, a rotational movement is caused by the connection of rocker 105 to pivot point 150. The rotational movement of rocker 105 causes channel 120 to be rotationally moved in a curvilinear path around pivot point 255 of crank 125. The rotational movement of channel 120 may additionally cause channel 120 to move through the plane that is parallel to the top surface of rocker switch 100, which intersects pivot point 255. The rotational movement of channel 120 forces a rotational movement of pin 115 from the first end of channel 120 toward a second end of channel 120. The rotational movement of channel 120, and pin 115, causes a lateral movement of the mechanical on/off components 130, inside of housing 140, thereby closing the circuit and activating the rocker switch 100. To deactivate rocker switch 100, end portion 205 is depressed. The depression of end portion 205 causes a rotational movement in the opposite direction to the movement created upon the initial depression of rocker 105. This causes a rotational movement of pin 115 back toward the first end of channel 120, deactivating rocker switch 100.

(15) Housing 100 has a curvilinear portion 210 located near the substantially curved portion 145. Curvilinear portion 210 extends from housing 100 and is sized approximately the same height as that of lip 110. This allows switch 105, with lip 100, to create a flat surface with housing 100 through curvilinear portion 210.

(16) As best seen in FIGS. 3, 4, 7 and 8, side views of rocker switch 300, having substantially the same components to that of rocker switch 100, are shown. Rocker switch 300 operates in a substantially similar manner to that of rocker switch 100. Rocker switch 300 contains a housing 340 that houses the mechanical and electrical components of rocker switch 300. Rocker switch 300 has an external rocker 310 which extends from housing 340. Similar to rocker 105 of rocker switch 100, rocker 305 has a substantially curved portion 345. However, rocker 305 does not have a lip and rocker 305 forms a substantially flat surface opposite to curved portion 345.

(17) Housing 340 contains curvilinear portion 335 and curvilinear portion 345 located on opposite sides of rocker 305, however, since rocker 305 does not have a lip, the height of curvilinear portion 335 and 345 is less than the height of curvilinear portion 210 from FIG. 2. When rocker 305 is depressed, as there is no lip, rocker 105 forms a flat surface with curvilinear portions 335 and 345.

(18) This rocker switch has the advantage in that it creates a substantially smaller profile, from the surface of the device it is installed on. Additionally, it has a substantially reduced depth inside of the device, allowing it to be placed in smaller devices, and more varied locations. Finally, the rocker eliminates a bulky component required by prior art rocker switches. The rocker is cheap to manufacture, and is easily integrated with existing electrical components.

(19) It would be appreciated by those skilled in the art that various changes and modification can be made to the illustrated embodiments without departing from the spirit of the present invention. All such modifications and changes are intended to be covered hereby.
