US4339833A — Reciprocating hydro-massage apparatus

Claim 1

Independent Claim 105 words

A reciprocating hydro-massaging apparatus comprising: a housing having at least one wall with an elongated opening provided therein, said wall having a front face and a rear face; a nozzle reciprocably mounted in said housing adjacent said rear face of said wall in fluid communication with said elongated opening; means coupled to said nozzle for reciprocating it with respect to said elongated opening; and means connected to said nozzle for supplying a massaging fluid to said elongated opening, whereby a user of said apparatus may position a body part adjacent said elongated opening and said front face of said wall for massaging said body part.

Claim 2

Dependent Claim 105 words

A reciprocating hydro-massaging apparatus comprising: a housing having at least one wall with an elongated opening provided therein, said wall having a front face and a rear face; a nozzle reciprocably mounted in said housing adjacent said rear face of said wall in fluid communication with said elongated opening; means coupled to said nozzle for reciprocating it with respect to said elongated opening; and means connected to said nozzle for supplying a massaging fluid to said elongated opening, whereby a user of said apparatus may position a body part adjacent said elongated opening and said front face of said wall for massaging said body part.

Claim 3

Dependent Claim 19 words

An apparatus as recited in claim 1 wherein said wall comprises the encompassing side wall of a hot tub.

Claim 4

Dependent Claim 40 words

An apparatus as recited in claim 1 including a flexible diaphragm affixed to said front face of said wall in fluid-tight relationship with said elongated opening, whereby said fluid will flex said diaphragm into massaging relationship with said body part.

Claim 5

Dependent Claim 49 words

An apparatus as recited in claim 3 including a seat having a backrest for supporting said user's back, said backrest including a front surface and a rear surface and means mounting said housing to said backrest with said diaphragm in massaging relationship with said rear surface of said backrest.

Claim 6

Dependent Claim 62 words

An apparatus as recited in claim 1 wherein said reciprocating means comprises: a double helix screw having first and second ends; means for journalling said ends in said housing in a manner such that the major axis of said screw lies parallel and adjacent to the major axis of said elongated slot; and a motor connected to said screw for rotating it.

Claim 7

Dependent Claim 14 words

An apparatus as recited in claim 5 wherein said motor is an electric motor.

Claim 8

Dependent Claim 21 words

An apparatus as recited in claim 5 wherein said motor is a fluid driven motor and wherein said screw is stationary.

Claim 9

Dependent Claim 101 words

In combination with a hot tub including an encompassing sidewall having an inner surface and an outer surface and an incoming water supply, the improvement which comprises: A. An elongated slot in said sidewall; and B. A reciprocating massaging apparatus affixed to the outer surface of said encompassing sidewall in fluid communication with said elongated slot, said apparatus comprising: 1. a housing having an open front, a rear wall, an open top and a bottom wall; 2. means affixing said housing to the outer surface of said encompassing sidewall with the open front of said housing communicating with said elongated slot;

Claim 10

Dependent Claim 101 words

In combination with a hot tub including an encompassing sidewall having an inner surface and an outer surface and an incoming water supply, the improvement which comprises: A. An elongated slot in said sidewall; and B. A reciprocating massaging apparatus affixed to the outer surface of said encompassing sidewall in fluid communication with said elongated slot, said apparatus comprising: 1. a housing having an open front, a rear wall, an open top and a bottom wall; 2. means affixing said housing to the outer surface of said encompassing sidewall with the open front of said housing communicating with said elongated slot;

Claim 11

Dependent Claim 43 words

a partition mounted in said housing adjacent said open top; 4. a hydro-jet-type nozzle; 5. means reciprocably mounting said nozzle in said housing in fluid communication with said elongated slot; and 6. a flexible conduit connecting said nozzle to said incoming water supply.

Claim 12

Dependent Claim 43 words

a partition mounted in said housing adjacent said open top; 4. a hydro-jet-type nozzle; 5. means reciprocably mounting said nozzle in said housing in fluid communication with said elongated slot; and 6. a flexible conduit connecting said nozzle to said incoming water supply.

Claim 13

Dependent Claim 15 words

An improvement as recited in claim 8 including means for supplying air to said nozzle.
