[5 7 ABSTRACT A drinking fountain and bubbler or nozzle structure therefor. The drinking fountain is fully recessed into an opening provided therefor in a building wall, and it has a drinking chamber closed by rearwardly converging sidewalls, top and bottom walls, and rear wall but open along its front wall or face to provide access into its interior. A bubbler structure is mounted in one of the sidewalls and has a face substantially contiguous therewith. The bubbler structure has a nozzle chamber open along its face and equipped along the base with a nozzle through which a stream of water is directed for oral interception within the drinking chamber. The nozzle chamber, nozzle, and base wall of the chamber have specialized orientations and dispositions that cause the water trajectory to be upwardly, inwardly, and rearwardly directed with respect to the drinking chamber, and that also cause the drinking fountain and bubbler structure to be substantially squirt proof by finger manipulation of children and the like, The fountain and bubbler structure also have vandal resistive features and characteristics.

9 Claims, 5 Drawing Figures RECESSED DRINKING FOUNTAIN AND BUBBLER THEREFOR This invention relates to a drinking fountain or the like and, more particularly, to a drinking fountain and bubbler structure therefor from which fresh water discharges along a trajectory oriented for oral interception and if not used falls into and collects within a basin from which the water discharge is carried to waste. A drinking fountain embodying the present invention is especially useful as a fully recessed fountain substantially concealed within an opening provided for this purpose in a building wall.

A general object of the present invention is to provide an improved drinking fountain and bubbler or nozzle structure therefor which is substantially splash proof in ordinary use, is substantially squirt proof by finger manipulation of children and the like, and is also resistive to vandalistic and other intentional attack especially as concerns the bubbler structure.

Further objects, among others, of the present invention are in the provision of an improved drinking fountain and bubbler structure of the character described in which the drinking fountain is of the fully recessed type defining a substantially closed drinking chamber that is open along the front or outer face of the fountain to permit access for drinking; in which the bubbler structure is recessed into one of the sidewalls of the fountain defining the drinking chamber thereof and is therefore unobtrusive and substantially concealed; in which the bubbler structure has a nozzle chamber and base wall closing the same the latter of which is angularly disposed from front to rear of the drinking chamber, is tipped downwardly and rearwardly relative to a horizontal plane, and is inclined upwardly and outwardly with the result that a nozzle terminating essentially adjacent the plane of such base wall is correspondingly oriented and disposed so that the trajectory of a water stream ejected therefrom is upwardly and inwardly toward the center of the drinking chamber, is angled rearwardly with respect thereto, and is tilted rearwardly so that the fountain is substantially splash proof during normal use thereof; in which the nozzle is located in very close proximity to the rear of the nozzle chamber which diminishes in width thereat, thereby making access to the nozzle very difficult and finger manipulation practicably infeasible so as to make the fountain and bubbler structure essentially squirt proof especially as respects directing water outwardly through the open front of the drinking chamber; in which the nozzle is the open end of a small tube or flow conduit terminating adjacent the upper exposed face of the base wall in the nozzle chamber, and in which the bubbler structure is small in physical dimensions, very unobtrusive, and is secured in place without screws and similar fasteners, thereby making installation convenient and rapid and also protecting the same against insertion of screwdrivers, pry bars and the like intermediate the bubbler structure and associated wall of the drinking fountain.

Additional objects and advantages of the invention, especially as concerns particular features and characteristics thereof, will become apparent as the specification continues.

An embodiment of the invention is illustrated in the accompanying drawing, in which:

FIG. 1 is a broken perspective view illustrating the upper portion of a fully recessed drinking fountain and bubbler therefor disposed in association with a building wall;

FIG. 2 is an enlarged broken horizontal sectional view taken along the line 2-2 of FIG. I;

FIG. 3 is a further enlarged broken face view of the bubbler taken along the plane 33 of FIG. 2;

FIG. 4 is a broken vertical sectional view taken along the line 4-4 of FIG. 3; and

FIG. 5 is a broken horizontal sectional view taken along the line 5-5 of FIG. 3.

The drinking fountain illustrated in FIG. I is denoted in its entirety with the numeral 10, and it is a fully recessed fountain adapted to be located within an opening 11 provided for this purpose in. a room wall or other building wall 12. In the form shown, the drinking fountain 10 is equipped with a refrigeration system (not shown) located behind a louvered panel 14-. As respects the present invention, it is of no significance whether the fountain I0 is or is not provided with refrigeration mechanism, nor is it pertinent as to how the flow of water for the fountain is controlled which, ordinarily, is by means of a manually manipulatable valve (not shown). In the fountain 10, a manual control 15 is provided for such valve, and the control 15 is adapted to be depressed to initiate the flow of water from the fountain nozzle.

The fountain 10 is provided with casing structure 16 that defines a drinking chamber 17 of sufficient size to enable the face and head of an individual to be placed at least partially therein to intercept a stream of water ejected from bubbler structure 18, generally as indicated in FIG. 1 by the broken line path associated with such bubbler structure. The chamber 17 is formed by transversely spaced, upwardly extending

sidewalls

19 and 20 which are associated adjacent the lower end of the chamber 17 with a somewhat concave bottom wall 21. The sidewalls l9 and 20 are similarly associated at the upper end of the chamber 17 with a top wall 22, and at their back edges they are connected with a rear wall 23. The sidewalls l9 and 20 are angularly disposed relative to each other and incline rearwardly and inwardly toward convergence so that the chamber 17 is somewhat wider along the outer wall thereof, as depicted in FIG. 1.

The bottom wall 21 is equipped with a conventional anti-splash ridge 24, and it is provided with a plurality of drain openings 25 communicating with a drain conduit 26 adapted to be connected to waste. As respects the present invention, components of the fountain 10 are standard and need not be considered. Similarly, the materials from which the fountain are constructed may be any suitable for this purpose as, for example, concrete, metals such as stainless steel, etc.

As illustrated most clearly in FIGS. 2 and 4, the bubbler structure 18 is recessed within an opening 27 struck or otherwise formed in the sidewall 19 of the fountain 10. In the particular fountain being considered, the opening 27 is located adjacent the lower forward corner portion of the wall 19, and the bubbler structure projects therethrough and extends into that portion of the wall space I. 1 defined between the tapering fountain wall 19 and facing edge of the room wall manner but advantageously without screws or rivets or similar fastening devices and, for example, the bubbler structure may be soldered or brazed to the wall 19 or it may be secured thereto by adhesive means such as one of the conventional and effective epoxy resin adhesives. The fountain itself may have a perimetric edge portion 29, as shown in FIGS. 1 and 2, which overlies the border of the wall opening 11 so as to provide an attractive and finished appearance for the installation.

The face 28 of the bubbler structure 18 is provided with an opening 30 therein that is elongated and, in more particular terms, is elongated in an upright direction so that it extends substantially from the top to the bottom of the face except for the marginal edge portions thereof overlying the fountain wall 19, as is most evident in both FIGS. 3 and 4. Thus, the opening 30 lies along the plane of the face 28 which, in the form shown, is in substantially parallel juxtaposition with the fountain wall 19. Projecting outwardly from the face 28 of the bubbler structure through the opening 27 in the fountain wall 19 are a base wall 31, side or

closure walls

32 and 34, and a rear wall 35. The

walls

31, 32, 34 and 35 define a nozzle chamber 36, and in the fabrication of the particular bubbler structure 18, it is a cast component in which the nozzle chamber 36 is formed, as part of the casting process, in a solid mass of material 37 formed integrally with the face 28. Accordingly, the bottom wall 31,

side closure walls

32 and 34, and rear wall 35 all lie within the interior of the block or mass 37 and are integral therewith and with each other.

Although such walls are integral, certain portions of each are distinguishable and as respects the same, the

closure walls

32 and 34 are spaced apart and generally parallel andtheir mergence with the rear wall 35 is along arcuate paths. The rear wall 35 is inclined downwardly and outwardly, as is best seen in FIG. 4, so that at its upper end it terminates in the opening 30 provided by the face 28 and at its lower end it is spaced from such opening and meets the base wall 31 at a substantial distance therefrom. The nozzle chamber 36 and various walls defining the same are angularly disposed with respect to the plane of the face 28 and plane of the fountain wall 19, and such angular dispositions are best described with reference to the base wall 31 which has the most complex disposition from which the orientations of the associated walls generally follow.

'Referring first to FIGS. 2 and 5, it will be observed that the base wall 31 is turned laterally so as to be angularly disposed with respect to the plane of the bubbler face 28 and angles outwardly and forwardly therefrom. Accordingly, the longitudinal axis of the base wall 31 angles inwardly and rearwardly relative to the drinking chamber 17 and sidewall 19 of the fountain (see FIG. 2) and generally follows the angular direction defined by the antisplash ridge 24 of the fountain. The base wall 31 is also tipped so that the plane thereof angles downwardly and rearwardly (as seen best in FIGS. 1, 3, and 4) so as to be angularly oriented relative to a horizontal plane passing through the bubbler structure. The base wall 31 is also inclined so as to extend generally along the direction of elongation of the opening 30 in the bubbler face 28, and in other terms, the base wall 31 is seen to be inclined outwardly and upwardly, as shown most clearly in FIGS. 3 and 4. By way of specific example, in a particular embodiment of the invention the base wall 31 of the bubbler structure angles outwardly and forwardly (see FIG. 2) such that the included angle defined by the intersection of the longitudinal axis of the base wall with the plane of the bubbler face 28 is of the order of 78 (i.e., the included angle between such longitudinal axis and the intersection of a line normal to the plane of the bubbler face 28 is of the order of 12); the included angle defined between the plane of the base wall 31 and a horizontal plane intersected thereby (see FIG. 3) is of the order of 12;

and the included angle defined by the intersection of the plane of the base wall 31 and plane of the face wall 28 (see FIG. 4) is of the other of 60. Since the base wall 31 along the exposed inner surface is generally rectangular except for the arcuate mergence thereof with the rear wall 35, the nozzle chamber 36 has a generally corresponding orientation and configuration with the base wall 31 closing the same and defining the lower extremity of the opening 30 in the bubbler face.

The base wall 31 is provided with a nozzle port 38 through which water is conducted for ejection through the opening 30, as indicated generally in FIG. 1. The axis of the port 38 is generally normal to the plane or the base wall 31 so that such port assumes the angular orientations and dispositions of such base wall. The port 38 is equipped with a nozzle which, in the form shown, is a flow tube or conduit 39 which extends completely through the nozzle port 38 and projects slightly above the plane of the base wall 31, as shown by the lip 40. In the exemplary structure noted hereinbefore, the lip 40 may project above the base wall 31 by approximately one-eighth of an inch. The flow conduit 39 is adapted to be connected to a source of water under pressure via the usual control valve which is manipulated by the button 15, and which source of water will also have any refrigeration apparatus disposed along the flow path thereof. The conduit 39 is secured to the mass or block 37 such as by being sweated or soldered to the circumjacent walls of the nozzle port 38.

The fountain 10 functions in the same general manner as any conventional fountain with no water flowing through the conduit 39 until the control button 15 for the valve is depressed. Upon such depression of the button 15, water is ejected through the nozzle opening defined by the lip 40 of the conduit 39 in a stream following an upward and inward trajectory along the length of the antishlash ridge 24 toward impingement thereupon. The bottom wall 21 of the fountain is necessarily somewhat concave with the lowermost point being adjacent the drain openings 25 so that all excess water is quickly drained from the bottom wall 21 into the drain conduit 26 for removal to waste. Not only is the trajectory of the water stream upwardly and inwardly oriented, it also angles rearwardly toward the rear wall 23 of the drinking chamber 17. Thus, the water discharge is away from the open front of the fountain toward the rear of the otherwise closed drinking chamber 17. In this reference, the stream tends to assume a tilted or angled orientation relative to a vertical plane because of the tipped rearward and downward inclination of the base wall 31 which not only augments the general rearward direction of the water stream but tends to reduce outward splashing from the ridge 24. The upward and outward inclination of the base wall 31 is effective to place the apogee of the water trajectory more nearly at the center of the drinking chamber 17 to facilitate oral interception of the stream. Accordingly, the described inclinations and angular dispositions of the trajectory completely compensate for the angular disposition of the sidewall 19 of the fountain.

The conduit 39 and nozzle port are disposed adjacent the rear wall 35, and the width of the nozzle chamber 36 decreases adjacent the rear wall 35 because of the curvature thereof at its mergences with the side closure walls 32- and 34. This orientation and arrangement of the nozzle conduit 39, nozzle chamber 36, and inclination of the rear wall 35 all taken together with the normal path of the trajectory make it exceedingly difficult for one to manipulate his fingers in and about the lip 40 to cause water to squirt from the nozzle especially toward the open front of the fountain. As a result, the fountain is essentially squirt proof" by intentional manipulation of the water stream, as well as being ordinarily splash proof respecting the escape of water through the open front of the fountain.

Moreover, the entire fountain l0 and especially the bubbler structure 18 thereof are substantially tamper proof in that the entire fountain except for the perimetric edge 29, control button 15, and louvered face 14 are all concealed within the wall opening 11; and essentially all of the bubbler structure 18 is concealed within or behind the fountain wall 19 except for the perimetric border portion of the bubbler face 28 which is contiguous with the exposed face of the fountainwall. Thus, the fountain and bubbler structure are very resistive to vandalism and intentional attack thereon.

By way of illustrating a specific structural exemplification of the invention, the following dimensions may be considered, but it should be understood that such dimensions are simply illustrative and are in no sense critical: The rough-in dimensions for the wall opening 11' may be 16% inches in width and 57 inches in height; the depth of the drinking chamber 17 may be approximately 1 lr inches from the outer surface of the flange 29 to the inner surface of the rear wall 23; the largest width ofthe drinking chamber 17 maybe 12 inches, the vertical center line of the bubbler structure 18 may be inset approximately 3 inches from the outer face of the flange 29; and the elevation of the conduit lip 40 at the center thereof may be approximately 2% inches from the level of the bottom wall 21 along the outer edge thereof at the exposed surface of the perimetric flange 29. The bubbler structure 18 may have a vertical height of approximately 2% inches with the maximum vertical dimension of the opening 30 being about 2% inches; the width of such bubbler structure across the face 28 thereof may be 1% inches and the width of the opening 30 about three-eighths of an inch; the axial length of the base wall 31 may be about 1% inches; and the conduit 39 may be one-fourth inch with the center thereof disposed approximately three-sixteenths of an inch from the back of the rear wall 35. The angular orientations and dispositions of the base wall 31 for such exemplary fountain and bubbler structure have been noted previously and will not be repeated.

While in the foregoing'specification an embodiment of the invention has been set forth in considerable detail for purposes of making a complete disclosure thereof, it will be apparent to those skilled in the art that numerous changes may be made in such details without departing from the spirit and principles of the invention.
