8 Claims. (Cl. 128-66) This invention relates to hydrotherapy apparatus, and more particularly to an improved circulator pump assembly adapted to be employed in bath tanks and tubs for the treatment of patients and to be used by nonpatients for the therapeutic effects to be derived from hydro-massage.
An object of the invention is to provide a compact and relatively light weight circulator pump assembly which may be readily moved from place to place and which may be positioned for use at any desired location within a bath tub, or the like.
A further object of the invention is to provide a circulator pump assembly particularly adapted for use in a tub or tank as hydrotherapy apparatus, with said assembly having a horizontally disposed outlet nozzle so supported with respect to the tub or tank as to permit, as by pedipulation, ready rotative positioning thereof about a vertical axis.
A further object of the invention is to provide a circulator pump of the type described having a nozzle assembly which is horizontally and rotatably movable, with said assembly being so formed and disposed with respect to the pumping element that it will remain in any given position of adjustment without any tendency to be moved therefrom by reaction force of the outlet flow from the nozzle.
A further object of the invention is to provide a circulator pump having an adjustably positionable nozzle assembly embodying novel foot-control means for both varying the directional position of the nozzle and the rate of outlet flow therethrough.
Still a further object of the invention is to provide in a pump of the type described a venturi-type outlet nozzle which itself serves as the movable element of the water flow control valve.
And yet a further object of the invention is to provide in association with the inlet side of a pump of the type described novel means for filtering the water delivered to the pumping element.
These and other objects and advantages of the invention will be apparent from the following description taken in conjunction with the drawings forming part of this specification, and in which:
Figure 1 is a sectional view of the pump of the invention, the motor housing being shown in side elevation;
Figure 2 is a view in perspective showing the components of the pump assembly; and
Figure 3 is a view in section taken along lines 3-3 of Figure 2.
With immediate reference to Figure 2, the apparatus of the invention comprises, broadly, a pump housing 10, an impeller-type pump element 12, a top 14 for the housing, and a nozzle assembly 16. In the housing 10, which is provided with a base portion 18 having a plurality of inlet apertures 20 and a channel-shaped rubber footing 22, there is formed an impeller chamber 24 having in communicaion therewith a pair of oppositely disposed and oppositely directed volute-shaped passageways 26. The
ice
The housing top 14 is provided with a plate portion 44 and a flow passageway portion indicated generally at 46 and shown in detail in Figure 3. The plate portion 44 of the housing top is provided with bolt holes 48 disposed in matching relation with bolt holes 50 formed in housing 10 whereby top 14 is secured to housing 10 by bolts, not shown. The flow passageway portion 46 of the housing top 14 has defined therein: apertures 52 disposed in overlying relation with the outer ends of volute-shaped passageways 26; radially directed flow passageways 54 communicating at their inner ends with a vertically disposed annular passageway 56, defined between the integral internal sleeve 58 and external shell 60 portions of flow passageway portion 46; and circumferentially spaced apertures 62 formed in external shell portion 60.
Formed within chamber 68 integral with member 66 is a frusto-conical valve seat 90. The passageway 92 formed in nozzle 80 serves as a venturi, said passageway having an outwardly flared rearward portion 94, a throat portion 96, and an outwardly tapered forward portion 98.
Sealing rings are disposed within annular grooves formed in member 66, and a snap ring 102 carried within annular groove 104 formed in the upper end of sleeve 58 serves to retain the nozzle assembly against any appreciable vertical movement.
An electrical motor of the submersible type, not shown, is disposed within a sealed casing 106, said casing being provided with a carrying bail 108. Depending from the casing 106 is a stationary double diametral hub 110 which is supported on internal shoulder 112 formed in sleeve 58 and secured to said sleeve, as by set screws 114. Motor shaft 116 extends through hub 110, and hub portion 118 of the impeller 12 is secured to said shaft against relative rotation therewith, as by a key, not shown, and against endwise movement with respect to said shaft by shoulder 118 integral with said shaft, thrust washer 120 and screw 122.
When the motor is energized to drive the impeller 12, water is drawn through the ports and housing opening into the eye of the impeller to be centrifugally urged outwardly by the impeller blades 124 into the voluteshaped passages 26. The pressurized water then follows the following course before issuing as a jet stream from nozzle upwardly through apertures 52 in the fluid passageway portion 46 of housing top l4; radially inwardly through passages 54; upwardly through annular passageway 56; radially outwardly through ports 62 into chamber 68; and around valve seat and through the nozzle 80.
Means are provided in the circulator pump assembly described for enabling the user of the apparatus to control with his feet both the rate of outlet flow of water and the directional orientation of the outlet flow, thus enabling the user to accomplish these adjustments without shifting his position. sembly 16 is provided with a pair of oppositely directed foot bars 134 (Figure 2) whereby this rotatable assembly may be foot-steered, or oriented, and nozzle 80 is provided with a foot controlled handle comprising ring 138 and equi-spaced radially extending fingers 140 which are sufficiently spaced apart to enable the user to insert a toe between adjacent ones and thereby impart a rotary adjustment motion to nozzle 80. Rotary motion of nozzle 80 in a clockwise, with reference to Figure 2, direction serves to thread the nozzle inwardly of nozzle housing 78 to bring that internal wall portion of the nozzle which defines the outwardly flared rearward portion 94 of nozzle passage 92 into valve closing engagement with seat 90. The nozzle assembly 16 is further provided with a downwardly projected lug 142 serves, in association with the side edges of portion 46 of housing top 14, as a stop member to limit the degree of pivotal movement which may be imparted to the nozzle assembly.
It will be appreciated that the arrangement of the nozzle assembly is such, i. e. the ring-shaped member 66 and is to say, the nozzle will not kick back to a given position when adjusted to another, and thus it is not necessary to employ any means to hold the nozzle in a given position of adjustment. If such holding means were needed, free pedipulation of the apparatus would be prevented.
From the foregoing description, it will be apparent that the hydrotherapy apparatus of the invention enables the accomplishment of the objects initially setforth herein, and while a specific embodiment of the apparatus has been illustrated and described itis to be understood that all substantial equivalents thereof are considered to be within the spirt and scope of the invention.
