Description:
The present invention relates to urinal structures and more particularly to such urinal structures movable between a storage position and an in-use position.

It is well known that urine has an extremely rapid decay rate and produces a most disagreeable ordor. It has been found that a urinal structure producing a film of running water for flow over urine receiving surfaces is effective to eliminate or substantially reduce an odor from decaying urine.

The principal objects of the present invention are: to provide a urinal structure which is movable between a storage position and an in-use position wherein the movement to the in-use position effects discharging of a film of flushing fluid or running water over interior surfaces of a urine receiving receptacle; to provide such a urinal structure particularly adapted to eliminate or substantially reduce odors associated with the use thereof; to provide such a urinal structure movable relative to a vertical surface and between a storage position and an in-use position and which has a lid movable between a position covering an opening in an upper portion thereof and a position exposing the opening in response to movement of the urinal structure; to provide such a urinal structure having a compact housing which encloses operating parts when in the storage position and during movement to the in-use position thereby protecting same from vandalism; to provide such a urinal structure which is selectively movable to an in-use position conforming to the height of a person using same thereby accommodating individuals of various heights; to provide such a urinal structure having a trap in a drain to a sewer or other fluid disposal means which is operative at all times and in all positions; to provide such a urinal structure having a valve controlling flow of flushing fluid into the urinal which is pressure actuated to interrupt flow when the urinal structure is in the storage position and which requires positive action to permit flow of flushing fluid into the urinal structure; to provide such a urinal structure which is swingable outwardly from a vertical surface and has a lid movable between a position covering an opening in an upper portion thereof and a position exposing the opening in response to movement of the receptacle between the storage position and the in-use position; and to provide such a urinal structure which automatically effects flow of flushing fluid over urine receiving surfaces and which is sanitary in use, easily installed, attractive in appearance, positive in operation, durable in construction, economical to manufacture, and particularly well adapted for the proposed use.

Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings wherein are set forth by way of illustration and example certain embodiments of this invention.

Referring more in detail to the drawings:

As required, detailed embodiments of the invention are disclosed herein, however, it is to be understood that the disclosed embodiments are merely exemplary of the invention which may be embodied in various forms. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting but merely as a basis for the claims actually defining the scope of this invention. The disclosure hereof is presented only as a representative basis for teaching one skilled in the art to variously employ the present invention in virtually any appropriate detailed structure.

In the disclosed embodiment of the present invention, the reference numeral 1 generally designates a urinal structure having portions movably mounted relative to a generally vertical surface 2 for movement between a storage position 3 and an in-use position 4. The urinal structure 1 includes a receptacle 5 movably mounted relative the surface 2, said receptacle having an opening 6 in an upper portion thereof and a lid 7 movable between a position covering the opening 6 and a position exposing the opening 6 in response to movement of the receptacle 5 between the storage position 3 and the in-use position 4. A water discharge member 8 is mounted adjacent the receptacle opening 6 for communicating flushing fluid into the receptacle 5 and over interior surfaces thereof. The water supply is activated in response to movement of the receptacle 5 to the in-use position.

The illustrated urinal structure 1 has a housing to enclose the operative parts and all plumbing lines, valves, and the like and the housing includes a fixed upper portion 9 and a movable lower portion 10. The fixed upper portion 9 is defined by a generally arcuate front wall 11 and spaced end walls 12 and 13 defining a hood-like structure having an opening covering an upper end of the movable lower portion 10.

The movable lower portion 10 of the urinal structure 1 includes the receptacle 5 in the form of a urine receiving portion or compartment defined by a side wall 14 having upper peripheral edge portions thereof defining the opening 6 and a lower end portion 15 having means communicating therewith for conveying fluids including urine and flushing fluids therefrom, as later described.

The movable lower portion 10 of the urinal structure housing includes an upper or top wall 16 and a lower or bottom wall 17 with end or side walls 18 and 19 extending therebetween and with the walls 16, 17, 18, and 19 supporting the side wall 14 of the receptacle 5 and having respective edges of the walls 16, 17, 18, and 19 terminating adjacent the vertical surface 2 to define a compartment behind the urine receiving portion and enclosing means for effecting movement of the receptacle 5 between the storage position 3 and the in-use position 4 and means for effecting flow of flushing fluid to the water discharge member 8 and into the urine receiving portion or compartment defined by the side wall 14.

The movement effecting means includes an outwardly extending member or arm 20 which has one end thereof suitably secured to one of the end or side walls of the lower portion 10, for example side wall 18, and a shaft or hanger 21 pivotally or hingedly mounted on the other or outstanding end. The shaft or hanger 21 has a suitable foot receiving member or stirrup 22 on a lower end thereof whereby engagement of a foot within the foot receiving member 22 and a downward pressure thereon is effective to move the lower portion 10 of the receptacle 5 vertically along the vertical surface 2, as later described.

A plurality of vertically spaced guide members 23 are mounted on the vertical surface 2 or to a suitable backing member secured thereon and each have a plurality of vertically extending and laterally spaced apertures 24 extending therethrough and the apertures 24 in adjacent guide members 23 are vertically aligned to receive portions of a generally vertically extending frame 25 mounted on the movable lower portion 10 of the urinal structure 1 for guiding same during generally vertical movement thereof.

The illustrated frame 25 has a plurality of laterally spaced upright members 26 each received with respective vertically aligned apertures 24 in the guide member 23 and having upper and lower ends thereof suitably supported on the upper or top wall 16 and the lower or bottom wall 17 respectively of the movable lower portion 10. The upright members 26 each have generally curved or arcuate portions 27 extending outwardly from the vertical surface 2 and vertically spaced along the upright members 26 to be within the apertures 24 when the lower portion 10 of the urinal structure 1 is in the storage position 3 thereby effecting positioning respective peripheral edges of the walls 16, 17, 18, and 19 adjacent and in close proximity to the vertical surface 2 or the backing member on the vertical surface 2.

When the curved or arcuate portions 27 of the upright members 26 are moved out of the apertures 24 in the guide members 23, a spacing is effected between the vertical surface 2 and the lower portion 10 during movement thereof between the storage position 3 and the in-use position 4. The guide members 23 each have resilient frame engaging members 28 mounted thereon and positioned to be in engagement with the upright member 26 of the frame 25 to effect substantially uniform vertical movement of the frame 25 and the lower portion 10 of the receptacle 5 during movement thereof between the storage position 3 and the in-use position 4 and return to the storage position 3.

Resilient means extending between the vertical surface 2 or a backing member mounted thereon and a lower portion of the urinal structure 1 are provided for urging the lower portion 10 toward the storage position 3. In the illustrated structure, a bracket 29 is mounted on the backing member or vertical surface 2 and has one end of one or more resilient members 30 each having the other ends thereof suitably connected thereto with the resilient members 30 each having the other ends thereof suitably connected to the movable lower portion 10 at a point below the bracket 29 when in the storage position 3. In the illustrated structure, the movable lower portion 10 has wall portions defining a closure portion 31 depending from the lower or bottom wall 17 thereof to enclose a suitable discharge flow member, as later described, and the resilient member or members 30 have the lower ends thereof connected to the wall portions defining the closure portion 31 and extend through a suitable slot or opening in the lower or bottom wall 17 of the movable lower portion 10.

The lid 7 is illustrated as having an upper portion 32 hingedly supported on the fixed upper portion 9 of the urinal structure 1 and a lower portion 33 hingedly supported on the upper portion 32 of the lid 7. The upper and lower portions 32 and 33 of the lid 7 are in engagement with and supported on the water discharge member 8 when the lid 7 is in a closed or opening covering position.

Movement of the lower portion 10 of the urinal structure 1 away from or downwardly from the fixed upper portion 9 is effective to move the upper and lower portions 32 and 33 of the lid 7 to a folded position exposing the opening 6. In the illustrated structure, an upper edge of the upper portion 32 of the lid 7 is suitably hingedly mounted on a lower edge of the fixed upper portion 9 and a suitable linkage 34 extends between and has portions thereof connected to an ear or projection 35 extending from the side wall 14 and to the upper portion 32 of the lid 7 to effect movement of the upper and lower portions 32 and 33 of the lid 7 in response to movement of the lower portion 10 and receptacle 5.

The illustrated water discharge member 8 is mounted on the upper edges of the side wall 14 and extends around the opening 6 to the urine receiving compartment thereby framing same for communicating flushing fluid into the receptacle 5. The water discharge member 8 has a flow passage 36 extending longitudinally therethrough and having an inlet 37 to receive a suitable flushing fluid, such as water, for discharge into the receptacle 5 through a suitable outlet or escape passage 38 having a discharge end positioned to direct a film of running water over urine receiving surfaces within the urine receiving compartment of the receptacle 5.

A flexible flow member 39 has one end thereof communicating with a suitable source of flushing fluid (not shown) and an other end thereof communicating with the inlet 37 to the flow passage 36 of the water discharge member 8. A flow control valve 40 is positioned in the flow member 39 and has suitable portions movable between a flow permitting position and a flow interrupting position.

It is desirable that the movable portions of the control valve 40 be operative in response to fluid pressure to interrupt flow therethrough when the urinal structure 1 is in the storage position 3 and which requires positive action to permit flow of flushing fluid into the receptacle 5. In the illustrated structure, a plunger or shaft 41 is connected to the movable portions and extends exteriorally of the flow control valve 40 for selective engagement therewith by a lever 42 pivotally mounted on the backing member or vertical surface 2 and having a portion thereof engageable with the shaft or plunger 41 of the flow control valve 40.

The plunger or shaft 41 is engaged by the lever 42 in response to movement of the lower portion 10 of the urinal structure 1 from the storage position 3 toward the in-use position 4. In the illustrated structure, the ear or projection 35 mounted on the movable lower portion 10 of the urinal structure 1 engages the lever 42 and moves same toward the backing member or vertical surface 2 and into engagement with an exterior end of the plunger or shaft 41 to thereby move the movable portions of the flow control valve 40 to a flow permitting position thereby effecting flow of flushing fluid into the urine receiving compartment or receptacle 5 during movement from the storage position 3 toward the in-use position 4 and during return to the storage position 3 until the ear or projection 35 clears the lever 42.

The flushing fluid and urine mixed therewith are conveyed from the urine receiving compartment or receptacle 5 by flowing outwardly through a waste opening or aperture 43 in the lower or bottom wall 17 of the lower portion 10 by flowing into a suitable flow trap 44 in a waste flow member or conduit 45 communicating with sanitary disposal means (not shown). The flow member 45 has a flexible portion within the closure portion 31 of the receptacle 5 to permit movement of the lower portion 10.

It is desirable to provide fluid collecting means to receive possible leakage from the flow control valve 40, such as around the plunger or shaft 41, and convey the collected fluid through a suitable flow member 46 extending between and having respective opposite ends connected to a drip cup 47 positioned adjacent the control valve 40 and to the flow trap 44.

In using a urinal structure, constructed as illustrated and described, a person desiring to use same positions one foot thereof in the foot receiving member or stirrup 22 and downwardly moves same thereby moving the lower portion 10 and receptacle 5 downwardly parallel with the vertical surface 2 by moving the upright members 26 of the frame 25 downwardly through the vertically aligned apertures 24 of the guide members 23. The receptacle portion of the urinal structure 1 is thereby selectively movable to an in-use position conforming to the height of the person using the urinal structure 1 thereby accommodating individuals of various heights. Downward movement of the ear or projection 35 moves the linkage 34 to pivot the upper portion 32 of the lid 7 outwardly from the opening covering position to a position extending generally upwardly from the fixed upper portion 9 of the urinal structure 1 thereby moving the hingedly mounted lower portion 33 of the lid 7 to a folded position thereby exposing the opening 6 in the receptacle 5. The ear or projection 35 engages the lever 42 during downward movement of the movable lower portion 10 thereby moving the plunger or shaft 41 to adjust the movable portions of the flow control valve 40 thereby permitting flow of suitable flushing fluid through the flexible flow member 39 and into the flow passage 36 of the water discharge member 8 for effecting a flow of flushing fluid in the form of a film of running water over urine receiving surfaces of the receptacle 5, said flow continuing until the ear or projection 35 is moved out of engagement with the lever 42, as during return to the storage position 3.

FIGS. 4 to 7 inclusive illustrate a modified urinal structure 50 which is swingable outwardly from a storage position 51 adjacent a vertical surface 52 or a backing member mounted thereon to an in-use position 53. The modified urinal structure 50 includes a receptacle 54 having an opening 55 in an upper portion thereof and a lid 56 is movable between a position covering the opening 55 and a position exposing the opening 55 in response to movement of the receptacle 54 between the storage position 51 and the in-use position 53.

The illustrated modified urinal structure 50 has a housing to enclose the operative parts and plumbing items when in the storage position and the housing has a front wall 57 and spaced end or side walls 58 and 59 extending rearwardly from opposite ends thereof and a rear or back wall 60 extending between the end or side walls 58 and 59 to define the receptacle 54. Exerior surfaces of the end or side walls 58 and 59 have projections 61 and 62 respectively extending outwardly therefrom to be engaged by the lid 56, as later described.

The urinal structure 50 has a lower end portion thereof hingedly mounted on the vertical surface 52 or a backing member mounted thereon whereby the upper portion of the receptacle 54 is swingable outwardly from the vertical surface 52 to the in-use position 53. In the illustrated structure, ears 63 and 64 extend outwardly from the vertical surface 52 or backing member and a shaft or pin 65 extends through the ears 63 and 64 and through lower ends of the end or side walls 58 and 59 to thereby hingedly mount the lower end portion of the urinal structure 50 on the vertical surface 52.

It is desirable to maintain the modified urinal structure 50 in the storage position 51, therefore, a suitable resilient member 66 in the form of a tension spring extends between and has opposite ends thereof secured to the vertical surface 52 and to the back wall 60 of the receptacle 54 for urging same toward the vertical surface 52.

Movement of the urinal structure 50 outwardly from the vertical surface 52 is effected by rotating the shaft or pin 65 and in the illustrated structure, an elongated bracket 67 has one end thereof suitably secured to the urinal structure 50, as by having arms 68 and 69 of the bracket 67 each with one end thereof suitably secured to the end of side walls 58 and 59 respectively and the other end thereof suitably secured to the shaft or pin 65 whereby rotation of the shaft or pin 65 effects swinging of the upper portion of the urinal structure 50 outwardly from the vertical surface 52.

An arm 70 has one end suitably secured to the shaft or pin 65, as by welding, and extends transversely outwardly therefrom and means are mounted on the arm 70 and extend therefrom to be engaged by a user of the modified urinal structure 50 to move the arm 70 and thereby the receptacle 54 outwardly from the vertical surface 52 to the in-use position. In the illustrated structure, a hanger 71 is suitably mounted on an outstanding end of the arm 70 and has a foot receiving member or stirrup 72 mounted on a lower end thereof. The foot receiving member or stirrup 72 may be moved into engagement with a floor surface, therefore, suitable wheels 73 are rotatably mounted on the foot receiving member or stirrup 72 to permit movement of same along the floor without damage to the surface thereof.

The illustrated lid 56 has an upper portion 74 hingedly supported on the vertical surface 52 or a backing member thereon and has cooperating means thereon for engagement with the urinal structure 50 to support the receptacle 54 in the in-use position 53 and in the illustrated structure, the upper portion 74 of the lid 56 is defined by a front wall 75 and spaced end walls or flanges 76 and 77 extending from the front wall 75 and positioned adjacent exterior surfaces of the end or side walls 58 and 59 respectively whereby the upper portion 74 of the lid 56 encloses and covers an upper portion of the opening 56 of the receptacle 54 when in the storage position 51. The end walls or flanges 76 and 77 have elongated slots 78 and 79 respectively therein to receive the projections 61 and 62 extending outwardly from the end or side walls 58 and 59 of the modified urinal structure 50. The projections 61 and 62 are movable between opposite ends of the slots 78 and 79 thereby defining limits for the movement of the upper portion of the modified urinal structure and the receptacle 54.

The lid 56 is supported to effect movement thereof in response to movement of the urinal structure 50 and in the illustrated structure, the lid 56 is hingedly supported on the backing member or vertical surface 52 and includes a lower portion 80 hingedly mounted on a lower end or edge of the upper portion 74 thereof. In the illustrated structure, one or more arms 81 extend outwardly from the vertical surface 52 or backing member and have an upstanding or upright portion extending generally parallel with the backing member or vertical surface 52 for supporting an elongated shaft or pin 82 to be received within a recess 83 in an upper edge of the upper portion 74 of the lid 56. The front wall 75 of the upper portion 74 of the lid 56 engages a water discharge member 84 mounted on a rim of the opening 55 whereby outwardly swinging the urinal structure 50 and the receptacle 54 pivots the upper portion 74 of the lid 56 about the shaft or pin 82 and the projections 61 and 62 move along the slots 78 and 79 respectively until the projections 61 and 62 engage the lower ends of the slots 78 and 79 thereby supporting the receptacle 54 in the in-use position 53. When the receptacle 54 is in the in-use position 53, the lower portion 80 of the lid 56 is in a folded position in engagement with the end walls or flanges 76 and 77 of the upper portion 74 of the lid 56.

A flow member 85 communicates a source of flushing fluid with the water discharge member 84 and a flow control valve 86 is positioned in the flow member 85 and has a plunger or shaft 87 operatively connected to moving portions thereof and extends outwardly therefrom to be engaged by a lever 88 in response to movement of the receptacle 54 outwardly from the backing member or vertical surface 52.

In the illustrated structure, the lever 88 is pivotally mounted on the backing member or vertical surface 52 intermediate the ends thereof and one end portion of the lever 88 is engageable with the plunger or shaft 87 and the other end portion of the lever 88 has one end of a suitable resilient member 89 connected thereto with the other end of the resilient member 89 being connected to the back wall 60 of the receptacle 54 whereby outward movement of the back wall 60 stretches the resilient member 89 thereby pivoting the lever 88 to move the one end portion of same into engagement with the plunger or shaft 87 thereby moving the operative parts of the flow control valve 86 to a flow permitting position.

Use and operation of the modified urinal structure 50 is substantially similar to use and operation of the urinal structure 1 except for the outward swinging movement of the receptacle 54 and the mounting and construction of the lid 56 and its cooperation with the projections 61 and 62 for supporting the receptacle 54 in the in-use position 53.

It is to be understood that while I have illustrated and described certain forms of my invention, it is not to be limited to these specific forms or arrangement of parts herein described and shown.
