Patent ID: 7238144

Claim:
A facial and neck muscle exercising device for positioning against opposite corners of a person's mouth at an opening thereof to strengthen facial and mouth muscles, comprising: first and second mouth spreading arms which include respective end members that are spaced apart and adapted to engage the opposite corners of the person's mouth and respective elongate side members slidably connected together to vary the spacing of said end members; and an arm retaining device connected to said slide members adapted to control relative sliding movement of said mouth spreading arms to control said spacing and movement of said end members against the corners of the person's mouth as the muscles are flexed and relaxed during exercise, the slide member of the first mouth spreading arm has a slide bore which extends into a distal end thereof opposite its end member and the slide member of the second mouth spreading arm is adapted to be closely slidably received in said slide bore in a telescoping manner the arm retaining device is adapted to prevent complete separation of the mouth spreading arms by said first mouth spreading arm having an internal locking shoulder formed within the slide bore at the distal end of its slide member and the slide member of said second mouth spreading arm having at least one resilient retaining tab which extends radially outwardly from a distal end thereof opposite its end member, each retaining tab being adapted to flex radially inwardly to allow passage thereof into said slide bore and having an external locking shoulder adapted to engage said internal locking shoulder at full extension of said mouth spreading arms to prevent subsequent complete separation thereof.
