Abstract
Abstract The embodiment of the invention disclosed herein is directed to a visual reminder device for producing a visual display of tasks to be performed which are checked after their performance. The device comprises an elongated or base member having a plurality of spaced apart raised bosses extending therefrom and channels passing through the bosses. The central axis of the channels is spaced a predetermined distance from the surface of the elongated member. A toggle member or device has a tab portion extending from the space between the bosses and a cam portion extending into the space between the bosses. Resilient arms constituting integrally formed biasing and mounting means extend transversely of the cam portion preferably on both sides thereof and are captured within the channels of the spaced apart bosses such that manipulation of the tab causes the cam portion to engage the surface of the elongated member defining cam element engaging means in order to apply a biasing force to the resilient arms which, in turn, urge the toggle member or device over center to hold it in position on one side or the other of the raised bosses.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
287 words
In a visual reminder device, or the like, of the type having indicia thereon and a toggle mechanism associated with said indicia for movement between first and second indicating positions, the combination comprising: a base member, at least one boss formed on said base member and defining a channel having a central axis, cam element engaging means formed on said base member and being spaced from said central axis of said channel by a predetermined distance; a toggle member mounted to said base member for movement between first and second positions relative to said boss, said toggle member including a tab portion at one extremity for manual engagement and a cam portion formed integrally thereon at an opposite extremity including opposed tapering cam segment means with a reduced diameter portion at the free end thereof; and integrally formed biasing and mounting means in the form of at least one resilient arm member extending transversely of said cam and tab portion, said arm member being received in said channel for maintaining said toggle member in assembly with said base member and being spaced from the free extremity of said cam portion a distance greater than said predetermined distance, such that upon manipulation of said toggle member for movement between said first and second positions, said cam portion will be brought into engagement with said cam element engaging means, with continued movement urging said cam portion against said cam element engagement means and producing flexure of said resilient arm member thereby permitting said toggle member to move from said first position to said second position with a snap action, with said resilient arm member being retained in either said first or second position and prevented from inadvertent repositioning thereof.
Claim 2
Dependent Claim
287 words
In a visual reminder device, or the like, of the type having indicia thereon and a toggle mechanism associated with said indicia for movement between first and second indicating positions, the combination comprising: a base member, at least one boss formed on said base member and defining a channel having a central axis, cam element engaging means formed on said base member and being spaced from said central axis of said channel by a predetermined distance; a toggle member mounted to said base member for movement between first and second positions relative to said boss, said toggle member including a tab portion at one extremity for manual engagement and a cam portion formed integrally thereon at an opposite extremity including opposed tapering cam segment means with a reduced diameter portion at the free end thereof; and integrally formed biasing and mounting means in the form of at least one resilient arm member extending transversely of said cam and tab portion, said arm member being received in said channel for maintaining said toggle member in assembly with said base member and being spaced from the free extremity of said cam portion a distance greater than said predetermined distance, such that upon manipulation of said toggle member for movement between said first and second positions, said cam portion will be brought into engagement with said cam element engaging means, with continued movement urging said cam portion against said cam element engagement means and producing flexure of said resilient arm member thereby permitting said toggle member to move from said first position to said second position with a snap action, with said resilient arm member being retained in either said first or second position and prevented from inadvertent repositioning thereof.
Claim 3
Dependent Claim
51 words
A visual reminder device, or the like, as defined in claim 1 wherein there is provided a pair of bosses, spaced one from the other and defining co-axial channels and said toggle member includes a pair of oppositely extending resilient arm members, said arm members being received in said respective channels.
Claim 4
Dependent Claim
28 words
A visual reminder device, or the like, as defined in claim 2, wherein said toggle member and said resilient arm members are formed of a molded plastic material.
Claim 5
Dependent Claim
34 words
A visual reminder device, as defined in claim 2, wherein said channels include reduced diameter portions for receiving the ends of said resilient arm members for holding said ends firmly in a fixed position.
Claim 6
Dependent Claim
33 words
A visual reminder device, as defined in claim 4, wherein the ends of said resilient arms are defined by increased diameter portions sized to fit into said reduced diameter portion of said channels.
Claim 7
Dependent Claim
29 words
A visual reminder device, as defined in claim 1, wherein said arm member is rectangular in cross section with the major dimension thereof extending transversely of the cam segment.
Claim 8
Dependent Claim
87 words
A visual reminder device, or the like, as defined in claim 1, wherein said base member is formed of two molded plastic half sections having a parting line passing through said central axis, said boss being formed by opposing mating half circular portions cooperating to form said channel, said resilient arm member having an enlarged diameter portion at the end thereof, and said channel having a reduced diameter portion for receiving and firmly holding said enlarged diameter portion when said two molded half sections are secured together.
