This invention relates to the field of faucets for water delivery. More particularly, this invention relates to faucets configured to provide protection from injury as the result of abrupt descent upon the faucet due to slips, trips, falls or other accidents.
Bathtubs, showers, basins and their plumbing fixtures are common features in homes, schools, sports facilities, clubs and similar establishments. Often bathtubs are combined with a shower create a dual-use shower system for showers and baths. It is widely recognized that many injuries result from falling while taking a shower or bath. These injuries may range from inconsequential to life-threatening. Many precautions are sometimes undertaken to reduce the risk of falling, such as creating a no-slip surface or installing hand rails. Despite these efforts, bathtub injuries remain a serious concern. Small children may also fall while bathing. They often stand up while playing in the bathtub. This increases their risk of falling and injuring themselves.
A faucet configuration typically incorporates a metal spout that juts from the wall of the bathtub, shower, or basin. Due to its protruding nature, this metal spout is a major safety concern for all users whether they are washing, showering, or bathing. Any fall by a user or abrupt descent of a the head, torso or a limb that collides with this metal spout will almost certainly cause injury.
In dual-use systems that contain both shower and bath, there is sometimes a diverter valve that is used to change the flow of water between the spout and the shower head. This is often accessed by a valve available to the user. This valve head typically protrudes from the wall or from the spout itself and, like the spout, the valve head is also a safety concern in certain implementations.
What is needed therefore is an improved configuration of a faucet assembly that better protects users from injuries due to collisions with the faucet or diverter valve head.
With regard to the above, in one if its embodiments the invention provides a faucet assembly for installation on a substantially vertical surface. The faucet assembly includes a socket having (a) a wall, (b) a cup formed at least in part by the wall, (c) a socket inlet bore having a first end configured for attachment to a water source and a second end that terminates in the cup, and (d) a slot formed in the wall, with the slot having a first extension limit and a second extension limit. A rotatable plug is disposed in the cup, with the rotatable plug having a plug bore and the rotatable plug being sized to fit snugly in the cup. A spout in incorporated, with the spout having a discharge passage that is in fluid communication with the plug bore. The spout is attached to the rotatable plug through the slot, and the spout is rotatable between an extended position adjacent the first extension limit of the slot to an unextended position adjacent the second extension limit of the slot, and the position of the spout adjacent the second extension limit of the slot is downwardly directed to the unextended position. The socket bore and the plug bore are in fluid communication when the spout is positioned adjacent the first extension limit of the slot and the socket bore and the plug bore are out of fluid communication when the spout is positioned adjacent the second extension limit of the slot.
Another embodiment provides faucet assembly for installation on a substantially vertical surface, where the faucet assembly has a socket having (a) a wall, (b) a cup formed at least in part by the wall, (c) a socket inlet bore having a first end configured for attachment to a water source and a second end that terminates in the cup, and (d) a slot formed in the wall, with the slot having a first extension limit and a second extension limit. A rotatable plug is disposed in the cup, with the rotatable plug having a plug bore and the rotatable plug being sized to fit snugly in the cup and to rotate smoothly in the cup. A spout in also included, with the spout having a discharge passage that is in fluid communication with the plug bore. The spout is attached to the rotatable plug through the slot, and the spout is smoothly rotatable between an extended position adjacent the first extension limit of the slot to an unextended position adjacent the second extension limit of the slot, and the position of the spout adjacent the second extension limit of the slot is downwardly directed to the unextended position. The socket bore and the plug bore are in fluid communication when the spout is positioned adjacent the first extension limit of the slot.
Yet another embodiment provides faucet assembly for installation on a substantially vertical surface, where the faucet assembly includes a socket having (a) a wall, (b) a cup formed at least in part by the wall, (c) a socket inlet bore having a first end configured for attachment to a water source and a second end that terminates in the cup, and (d) a slot formed in the wall, the slot having a first extension limit and a second extension limit. A rotatable plug disposed in the cup, with the rotatable plug having a plug bore and the rotatable plug being sized to fit snugly in the cup. A spout is also provided, with the spout having a discharge passage that is in fluid communication with the plug bore. The spout is attached to the rotatable plug through the slot, and the spout is rotatable between an extended position adjacent the first extension limit of the slot to an extended position adjacent the second extension limit of the slot, and the spout is rotatable to a position that is on a substantially horizontal plane that is orthogonal to the substantially vertical mounting surface, and the position of the spout adjacent the second extension limit of the slot is downwardly directed to the unextended position. Further, the socket bore and the plug bore are in fluid communication when the spout is positioned adjacent the first extension limit of the slot. A nozzle is provided, where the nozzle is in flow communication with the discharge passage, wherein the nozzle is directed substantially vertically downward when the spout on the substantially horizontal plane that is orthogonal to the substantially vertical mounting surface.
Further advantages of the invention are apparent by reference to the detailed description in conjunction with the figures, wherein elements are not to scale so as to more clearly show the details, wherein like reference numbers indicate like elements throughout the several views, and wherein:
The present invention is directed generally toward plumbing fixtures and more specifically toward bathtub, shower, and basin faucets. Various embodiments provide a faucet assembly for installation with a bathtub, shower or washing basin system. The most preferred embodiments address safety concerns related to a person falling on the protruding spout by permitting the bathtub spout to rotate away from the faller's trajectory when the spout is impacted by the faller.
Some embodiments also incorporate the utility of a tub/shower diverter valve so that water flows into the tub or basin when the spout is in one operating position (typically perpendicular to the wall). Then, by rotating the spout to a second operating position (preferably downward and parallel to the wall), water is diverted to the shower head. In the most preferred embodiments, this is accomplished by use of a ball joint installed in the faucet assembly between the water pipe connection and the spout. This ball joint permits access to the water line and allows water to flow through the spout when the spout is positioned perpendicular to the wall. When the spout is rotated, preferably approximately ninety degrees downward, water is diverted from the spout to the shower head. In alternate embodiments the diverter may be activated by rotating the spout in other directions such as up, left, or right.
While the preferred embodiment is best applicable to dual use bathtubs with shower heads, the spout may also be used with bathtubs or basins which have no shower head. The protruding spout is still dangerous to falling bathers, particularly small children. Therefore the rotating aspect of the device is still attractive as a safety feature. In such embodiments, the assembly may still be configured to shut off the flow of water to the bathtub completely when rotated approximately ninety degrees from its standard operating position.
Further understanding of various embodiments may be discerned by a review of the figures.
Discharge tube 14 and ball 16 may be formed from unitary material stock, or may be fabricated separately and joined together as illustrated. A receptacle 18 is assembled with a receptacle cover 20. Receptacle 18 may be joined with receptacle cover 20 by such means as adhesives, threaded connections, pressure fitting or similar means that form a substantially leak-tight connection between receptacle 18 and receptacle cover 20. The geometry of receptacle 18 and receptacle cover 20 form a receptacle wall 22. A receptacle cup 24 is formed in part by receptacle wall 22 and in remainder by receptacle 18. Receptacle cup 24 is substantially spherical, and has plurality of geometric axes of rotation that pass through its center. Each axis of rotation is an imaginary line around which a hemi-circular arc of receptacle cup 24 is rotated to define the surface of the receptacle cup 24. Each axis of rotation passes through the geometric center of the receptacle cup 24.
A discharge passage 28 is provided in discharge tube 14, and a nozzle 30 directs fluid flow out of spout 12 in a direction substantially vertically downward when spout 12 is horizontal. A ball bore 32 passes through ball 16, and ball bore 32 is substantially axially aligned with discharge passage 28. Receptacle 18 comprises a receptacle inlet bore 34. Receptacle inlet bore 34 includes threading 36 at a first end and the second end of receptacle inlet bore 34 terminates in receptacle cup 24. The threading 36 is configured to conform to water pipe thread standards so that faucet assembly 10 may be connected to a pressurized water source (not shown). In alternative embodiments, threading 36 may be replaced with a configuration suitable for brazing, clamping, or other means of attachment to a water supply line.
In the embodiment of
As depicted in
Preferably, ball 16 is sized to fit snugly within receptacle cup 24, but with sufficient clearance to permit spout 12 to move within its range of travel, and to permit ball 16 to rotate within receptacle cup 24, with minimal manual forces. Most preferably, ball 16 rotates smoothly within receptacle cup 24. “Smoothly” is a feature wherein the force required to move the spout 12 between any two positions in the range of travel of spout 12 is substantially the same as the force required to move spout 12 between any other two positions in the range of travel of spout 12. However, in some embodiments a certain amount of “sticktion” (i.e., extra force needed at the start of travel) may exist naturally, and it may establish a tendency for the spout 12 to remain at any location in its range of travel. In some embodiments “sticktion” may be deliberately incorporated in order to induce the spout to remain at one or more designated locations in its range of travel. Such “sticktion” may be added deliberately by incorporating spring loaded detents or similar mechanisms which cause the spout 12 to snap set at preferred locations, such as “up” and “down.” Preferably, the apparatus should be designed so that a maximum torque of no more than approximately three to five foot-pounds (approximately a few tenths kilogram-meters) of torque is required to move the spout 12 from a given location to another location within the spout's range of travel, including torque necessary to overcome “sticktion” resistance and resistance from O-ring seal 44.
