Abstract
Abstract A free-standing oral hygiene device that is attachable to and detachable from a faucet member with one hand. An elongate flexible hose extends from the device to a hand-held wand which terminates in a nozzle that ejects a jet stream of water onto the teeth and gums of the user. When water pressure exceeds an adjustable preselected threshhold, a pressure relief valve opens so that the gums of the individual are not injured. A retaining clip member is depressed when the device is attached to the faucet, and released. When the retaining clip has been released, it holds the device to the faucet even when the water pressure from the faucet is very high. Removing the device is accomplished by depressing the retaining clip a second time and displacing the device downwardly. It can then be stored on a substantially level support surface as a free-standing unit.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
204 words
A dental hygiene device that directs water from a faucet onto dental surfaces, comprising: a hand-held wand member; a water-emitting nozzle means formed in said wand member; a fluidic device having a water-receiving first end and a water-discharging second end; an over-pressure relief valve means for opening said second end when water pressure inside said fluidic device is above a predetermined threshold pressure; a bore means formed in said fluidic device between its first end and its second end; an elongate, flexible conduit means that provides fluid communication between said fluidic device and said wand member; an adapter means having a first end substantially permanently secured to a discharge spout of a faucet and a second end releasably secured to said fluidic device; a quick release means, having an equilibrium state and a non-equilibrium state, that releases said first end of said fluidic device from said adapter means quickly when in its non-equilibrium state and which securely retains said fluidic device to said adapter means when in its equilibrium state; and said quick release means being a generally "U"-shaped retaining clip member having a pair of transversely spaced apart, flexible arm members, and wherein each arm member has an obtuse angle bend formed therein.
Claim 2
Dependent Claim
204 words
A dental hygiene device that directs water from a faucet onto dental surfaces, comprising: a hand-held wand member; a water-emitting nozzle means formed in said wand member; a fluidic device having a water-receiving first end and a water-discharging second end; an over-pressure relief valve means for opening said second end when water pressure inside said fluidic device is above a predetermined threshold pressure; a bore means formed in said fluidic device between its first end and its second end; an elongate, flexible conduit means that provides fluid communication between said fluidic device and said wand member; an adapter means having a first end substantially permanently secured to a discharge spout of a faucet and a second end releasably secured to said fluidic device; a quick release means, having an equilibrium state and a non-equilibrium state, that releases said first end of said fluidic device from said adapter means quickly when in its non-equilibrium state and which securely retains said fluidic device to said adapter means when in its equilibrium state; and said quick release means being a generally "U"-shaped retaining clip member having a pair of transversely spaced apart, flexible arm members, and wherein each arm member has an obtuse angle bend formed therein.
Claim 3
Dependent Claim
21 words
The device of claim 1, further comprising adjustment means for preselecting the pressure at which said over-pressure relief valve mans opens.
Claim 4
Dependent Claim
64 words
The device of claim 2, wherein said fluidic device includes a tubular main body portion, wherein an upper portion of said main body portion slidingly receives said adapter means therein when the device is assembled, and wherein said quick release means includes means engaging said adapter means and retaining it within said upper portion when said quick release means is in its equilibrium state.
Claim 5
Dependent Claim
32 words
The device of claim 3, wherein said adapter means includes an annular flange member that is engaged by said quick release means when said quick release means is in its equilibrium state.
Claim 6
Dependent Claim
21 words
The device of claim 4, where said upper portion has a pair of slot means formed therein, on opposite sides thereof.
Claim 7
Dependent Claim
71 words
The device of claim 5, wherein each of said arm members is positioned within a different slot means of said pair of slot means when said quick release means is in its equilibrium position, and wherein when said arm members are so positioned, said arm members overlie opposite portions of said adapter means annular flange member and thus prevent separation of said fluidic device main body portion from said adapter means.
Claim 8
Dependent Claim
44 words
The device of claim 6, further comprising means for causing said arm members to diverge with respect to one another and to thereby substantially withdraw from their respective positions within said slot means when said quick release means is not in its equilibrium position.
Claim 9
Dependent Claim
46 words
The device of claim 7, wherein said means for causing said arm members to diverge includes, at least in part, a pair of transversely spaced apart wedge members formed integral to said fluidic device and positioned forwardly of respective distal free ends of said arm members.
Claim 10
Dependent Claim
83 words
The device of claim 8, wherein said arm members are sufficiently elongate to position said retaining clip member in spaced relation to said fluidic device when said arm members are positioned within said slot means, whereby depressing said retaining clip member causes it to abut the fluidic device, in which position the arm members of said retaining clip member are driven out of their respective slot means by said wedge members so that said adapter means and said fluidic device may be separated.
Claim 11
Dependent Claim
35 words
The device of claim 9, further comprising a substantially flat-bottomed base means that supports said fluidic device in free-standing relation to a substantially level support service when said device is separated from said adapter means.
Claim 12
Dependent Claim
31 words
The device of claim 10, wherein said pressure relief valve means includes a biased valve member that is unseated only when water pressure within said fluidic device exceeds a predetermined threshold.
Claim 13
Dependent Claim
32 words
The device of claim 11, wherein said base means includes an integral, upstanding sleeve member that receives and supports a lower end of a biasing means that loads said biased valve member.
Claim 14
Dependent Claim
27 words
The device of claim 12, wherein said, main body portion and said sleeve member are screw threadedly engaged so that relative rotation therebetween provides said adjustment means.
Claim 15
Dependent Claim
33 words
The device of claim 13, further comprising a wand support member fixedly secured to an exterior sidewall of said fluidic device so that said wand member is supported thereby when not in use.
