Abstract
Abstract Apparatus (10) for massaging gums has a handle portion (12, 12') arranged for manipulating the apparatus (10) in order to impart an undulating motion to a substantially rigid massaging portion (14) arranged for insertion between adjacent teeth of a user of the apparatus. A coupling (16) connected to the handle portion (12, 12') and the massaging portion (16) articulate same to one another and permits the aforementioned undulating motion which causes a vibrating effect against the gum. The coupling preferably is in the form of a universal joint (42) in order to enhance the aforementioned undulating motion.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
168 words
Apparatus for massaging gums, comprising in combination: (a) handle means for manipulation of the apparatus; (b) a substantially rigid massaging means arranged for insertion between the teeth of a user of the apparatus; and (c) a universal joint coupling means interconnecting said handle means and said massaging means so that said massaging means normally extends perpendicularly from said handle means, said universal joint coupling means being cooperatively formed by a bore means provided transversely in said handle means and an axially extending shank and an enlarged head provided on said massaging means, said shank extending through the bore means of said handle means and being of slightly reduced diameter in relation to the bore means of said handle means to allow a free changing of the angular relationship between said massaging means and said handle means and to allow a swivel-like movement to be imparted to said massaging means upon insertion of said massaging means between the teeth of the user and upon manipulation of said handle means.
Claim 2
Dependent Claim
168 words
Apparatus for massaging gums, comprising in combination: (a) handle means for manipulation of the apparatus; (b) a substantially rigid massaging means arranged for insertion between the teeth of a user of the apparatus; and (c) a universal joint coupling means interconnecting said handle means and said massaging means so that said massaging means normally extends perpendicularly from said handle means, said universal joint coupling means being cooperatively formed by a bore means provided transversely in said handle means and an axially extending shank and an enlarged head provided on said massaging means, said shank extending through the bore means of said handle means and being of slightly reduced diameter in relation to the bore means of said handle means to allow a free changing of the angular relationship between said massaging means and said handle means and to allow a swivel-like movement to be imparted to said massaging means upon insertion of said massaging means between the teeth of the user and upon manipulation of said handle means.
Claim 3
Dependent Claim
31 words
Apparatus as defined in claim 1 wherein said massaging means further includes a tapered massaging element constructed from a soft yet rigid material selected for preventing damage to a user's gums.
Claim 4
Dependent Claim
33 words
Apparatus as defined in claim 1 wherein said handle means includes a straight portion and an offset portion, said massaging means being mounted on the offset portion by said universal joint coupling means.
Claim 5
Dependent Claim
258 words
Apparatus for massaging gums, comprising in combination: (a) handle means for manipulation of the apparatus, said handle means having opposed surfaces; (b) a massaging means for insertion between the teeth of a user of the apparatus, said massaging means including, I. a body of generally conical configuration, II. a flexible shank extending axially from the base of said conical body and being of reduced diameter in comparison to the base of said conical body, III. an enlarged head on the extending end of said shank; and (c) a universal joint coupling means interconnecting said handle means and said massaging means so that said massaging means normally extends substantially perpendicularly from one of the surfaces of said handle means, said coupling means including, said handle means having a bore formed transversely therethrough so as to provide a portion which divergingly opens onto the surface of said handle means which faces the base of said conical boby and having a countersunk area in the opposite surface of said handle means, said enlarged head being disposed in said countersunk area of said bore with said flexible shank extending through said diverging portion of said bore, said flexible shank having a diameter which is slightly smaller than the smallest diameter of said diverging portion of said bore to alow a free changing of the angular relationship between said massaging means and said handle means and to allow a swivel-like movement of said massaging means upon insertion of said massaging means between the teeth of the user and manipulation of said handle means.
Claim 6
Dependent Claim
258 words
Apparatus for massaging gums, comprising in combination: (a) handle means for manipulation of the apparatus, said handle means having opposed surfaces; (b) a massaging means for insertion between the teeth of a user of the apparatus, said massaging means including, I. a body of generally conical configuration, II. a flexible shank extending axially from the base of said conical body and being of reduced diameter in comparison to the base of said conical body, III. an enlarged head on the extending end of said shank; and (c) a universal joint coupling means interconnecting said handle means and said massaging means so that said massaging means normally extends substantially perpendicularly from one of the surfaces of said handle means, said coupling means including, said handle means having a bore formed transversely therethrough so as to provide a portion which divergingly opens onto the surface of said handle means which faces the base of said conical boby and having a countersunk area in the opposite surface of said handle means, said enlarged head being disposed in said countersunk area of said bore with said flexible shank extending through said diverging portion of said bore, said flexible shank having a diameter which is slightly smaller than the smallest diameter of said diverging portion of said bore to alow a free changing of the angular relationship between said massaging means and said handle means and to allow a swivel-like movement of said massaging means upon insertion of said massaging means between the teeth of the user and manipulation of said handle means.
Claim 7
Dependent Claim
23 words
Apparatus as claimed in claim 4 wherein said conical body, said shank and said enlarged head of said massaging means are integrally formed.
Claim 8
Dependent Claim
26 words
Apparatus as defined in claim 5 wherein said massaging means is formed of a soft yet rigid material selected for preventing damage to a user's gums.
