Description
HOSE NUT, WATER HOSE ASSEMBLY COMPRISING THE HOSE NUT AND SHOWER SYSTEM COMPRISING THE WATER HOSE ASSEMBLY
Related Application
This application claims priorities from U.S. Provisional Application No. 62/003,629 filed on May 28, 2014, German Utility Model application No. 20 2015 101 159.8 filed on 9 March 2015, and U.S. Non-provisional patent application No. 14/657,290 filed on 13 March 2015, the disclosures of which are incorporated herein by reference in their entirety.
Field of the Invention
This invention relates generally to fittings used for a shower network system and, more particularly, to a hose nut for connecting a shower head to a water hose, to a water hose assembly comprising the hose nut and to a shower system comprising the water hose assembly. The fittings of the invention allow to eliminate the need of drilling holes on the wall and of utilizing screws/bolts to mount the shower system.
Background of the Invention
Any discussion of the background art throughout the specification should in no way be considered as an admission that such background art is prior art, nor that such background art is widely known or forms part of the common general knowledge in the field in Australia or worldwide.
All references, including any patents or patent applications, cited in this specification are hereby incorporated by reference. No admission is made that any reference constitutes prior art. The discussion of the references states what their authors assert, and the applicants reserve the right to challenge the accuracy and pertinence of the cited documents. It will be clearly understood that, although a number of prior art publications are referred to herein, this reference does not
2015267876 19 Dec 2018 constitute an admission that any of these documents forms part of the common general knowledge in the art, in Australia.
Current shower systems typically comprise a water hose, one end of which is connected to a faucet and the other end of which is connected to a shower head. The shower head is usually held by a shower head holder mounted on the wall by fasteners such as screws/bolts for firmly securing the shower head onto the wall.
A common feature of this type of wall-mounted shower head is that the mounting of the shower head requires one or more holes to be drilled on the wall or even surface. By doing this, the wall surface would definitely be damaged and affected. Another disadvantage of this shower head is that it tends to be labor intensive to screw the shower head holder on the wall in place by screwing the screws and bolts or remove the holder from the wall. This is not a satisfactory task.
Therefore, the invention entails the task of creating a simple and cost-effective a shower system comprising a hose nut for a shower head that is able to be surely and stably attached onto a wall or even surface. The hose nut according to the invention eliminates the use of any kind of fasteners, such as screws/bolts and the need of drilling holes on the wall, with a consequence of maintaining the surface of the wall or even surface not to be damaged or affected. The shower system also allows easy adjustment of the height of the shower head, preferably by one hand, which is simple in structure.

Detailed Description of the Invention
While this invention is illustrated and described in preferred embodiments, the hose nut of the present invention may be produced in many different configurations, sizes, forms and materials.
Referring now to the drawings, Figs. 1 to 3 illustrate a hose nut 1 according to a first embodiment of the present invention. As shown in Fig. 3, the hose nut 1 comprises a nut body 3 having a throughbore 4 formed therein. The nut body 4 comprises a lower portion 5, a transition portion 6, an upper portion 7 and a magnetic element 8, preferably a flat magnet, mounted on a side of the lower portion 5. At least a part, for example an end portion, of the water hose 2, is received in the lower portion. The transition portion 6 is immovably secured to the lower portion 5, and the end portion of the water hose 2 is immovably secured to the transition portion 6, both by any one of the common manners in the art, such as threads and snap fit. The upper portion 7 for connection to a shower head (not shown) is arranged on the transition portion 6 in such a manner that the upper portion 7 is rotatable relative to the transition portion 6 around an axis 9 of the upper portion 7. The manner in which the upper portion 7 is rotatably connected to the transition portion 6 will be described in detail hereinbelow. In order to connect the upper portion 7 to the shower head, the upper portion 7 has internal threads formed on the inner surface of the throughbore thereof for mating engagement with corresponding threads formed on an outside of the shower head. In order to hang the shower head on a wall, a holding device 10 (see Fig. 19), such as a metallic or magnetic bar or panel, is mounted on the wall, and the hose nut 1 of the present invention is slidably attached to the
2015267876 19 Dec 2018 holding device 10 by a magnetic attraction force generated between the magnetic element 8 and the holding device 10. The holding device may be made of any material suitable to generate the magnetic attraction with respect to the magnetic element 8.
As shown in Fig. 3, in order to rotatably connect the upper portion 7 to the transition portion 6, the hose nut 1 further comprises a mandrel assembly 11 comprising a top flange 12 and a mandrel 13 extending downwardly from the top flange 12. The top flange 12 has a central throughbore formed therein, and the mandrel 13 has a central throughbore axially aligned with the throughbore of the top flange 12. The central throughbores of the top flange and the mandrel define a flow bore for water to pass through the mandrel assembly. The mandrel assembly 11 is disposed within the throughbore 4 of the nut body 3, with the flow bore of the mandrel assembly in communication with the throughbore of the nut body 3. The upper portion 7 of the nut body 3 comprises a shoulder 14 extending inwardly from an inner surface of the throughbore of the upper portion 7. The shoulder 14 defines an opening 15 that is configured for allowing passage of the mandrel 13 to be fixed to the transition portion 6 of the nut body 3 but preventing the top flange 12 from passing therethrough, such that the upper portion 7 is rotatable about the mandrel assembly 11 relative to the transition portion 6. In this embodiment, the opening 15 has a diameter that is larger than a diameter of the mandrel 13 but smaller than an outer diameter of the top flange 12, such that the mandrel 13 is allowed to pass through the opening 15 while the top flange 12 is not. The mandrel assembly 11 is fixed to the transition portion 6 by mating engagement between internal threads formed on the inner surface of the throughbore of the transition portion 6 and corresponding threads formed on an outside of the mandrel 13. To prevent leaking of water, a first O-ring seal 16 is placed between a bottom surface of the top flange 12 of the mandrel assembly 11 and the shoulder 14 of the upper portion 7 of the nut body 3. In other words, the first O-ring seal 16 is placed around the mandrel 13 of the mandrel assembly 11. For the same purpose, a second O-ring seal 17 is place between a top surface of the top flange 12 of the mandrel assembly 11 and the shower head, and a third O-ring
2015267876 19 Dec 2018 seal 20 is provided between the end of the water hose 2 and the transition portion 6 of the nut body 3.
In order to mount the magnetic element 8 onto the lower portion 5, an undercut portion 18 is formed on the side of the lower portion 5 of the nut body 3 (see Fig. 7D), and the magnetic element 8 is recessed and embedded in the undercut portion. In addition, a holder 19, preferably made of high density plastic materials such as PBT (polybutylene terephthalate) and POM (polyoxymethylene), is provided to define together with a surface of the undercut portion 18 a space in which the magnetic element 8 is enclosed. In this embodiment, the magnetic element holder 19 is in the shape of a frame comprising a flat surface and two side plates extending from the opposite ends of the flat surface, respectively. The flame and the surface of the undercut portion 18 together define a rectangular space for embedding the magnetic element 8 therein. When the two plates of the frame are mounted onto the lower portion 5 of the nut body 3, the flat surface of the holder 19 is flush with an outer surface of the lower portion 5.
The hose nut 1 and the water hose 2 thus form a water hose assembly 25 for connecting a faucet and a shower head, which can be easily and slidably attached to a holding device mounted on the wall. In some cases, the water hose assembly can be provided as an integral product, that is, with the water hose being integrally formed or prefabricated with the hose nut.
A hose nut 1 according to a second embodiment of the present invention is illustrated in Figs. 4 to 10C. The second embodiment of the present invention differs from the first embodiment in two aspects, which will be explained in detail as follows.
The first difference between the second and the first embodiments is that, in the first embodiment, the lower portion 5, the transition portion 6 and the upper portion 7 of the nut body 3 are aligned (as best seen in Fig. 3), while in the second embodiment, the transition portion 6 is secured at an angle to the lower portion 5 but is aligned with the upper portion 7. As shown in
2015267876 19 Dec 2018
Fig. 10C, the throughbore of the transition portion 6 of the second embodiment is formed to comprise a lower segment 21 and an upper segment 22 at an angle with each other. The lower segment 21 is aligned with the throughbore of the lower portion 5, while the upper segment 22 is aligned with the throughbore of the upper portion 7.
The second aspect in which the second embodiment differs from the first embodiment is that, in the second embodiment, two magnetic elements 8 are provided and are mounted in parallel on the side of the lower portion 5 of the nut body 3, as shown in Fig. 6. Correspondingly, the holder 19 is formed to comprise two compartments for accommodating the two magnetic elements respectively. Those skilled in the art will understand that the more magnetic elements are provided, the stronger the magnetic attraction force between the magnetic elements and the holding device will be. Therefore, the number of magnetic elements can be adjusted according to practical conditions, such as the total weight of the hose nut, without departing from the scope of the present invention.
Figs. 12 and 13 illustrate a hose nut according to a third embodiment of the present invention, which differs from the second embodiment only in that the transition portion 6 is accommodated within the lower portion 5, instead of being placed on top of the lower portion 5. Such a configuration provides a more compact structure and appearance for the hose nut.

As shown in Figs. 15 to 17, the locking mechanism comprises a button 32, a stopper 33 coupled to the button 32, a pair of posts 34 and a spring 35. The stopper is configured to engage with the upper portion thereby creating a lock therebetween for prevention of the rotation of the upper portion when the button is released, and to disengage from the upper portion to allow the rotation of the upper portion when the button is pressed.
In particular, the pair of posts 34 are integrally formed with the holder 19 and extend upwardly from a top of the holder 19 on opposite sides thereof. A hole 36 is drilled on each of the posts 34. The stopper 33 comprises an arc-shaped portion 37, a leg 38 extending downwardly from each of the two ends of the arc-shaped portion 37, and a pin 39 formed on an outer surface of each of the two legs 38. The two pins 39 are inserted into the two holes 36, respectively, such that the stopper 33 is pivotally mounted between the pair of posts 34. The stopper 33 further comprises a baffle plate 40 connecting the two ends of the arc-shaped portion 37, which baffle plate abuts against the button 32. The button 32 is movably mounted between the pair of posts 34 via a pair of protrusions 41 formed on opposite sides of the button 32 and received in a pair of slits 42 formed on the pair of posts 34, respectively. The slits 42 are sized to allow for free movement of the protrusions 41 therein along the length of the slits 42, when the button 32 is pressed or released. The length of the slits 42 is long enough to allow the button 32 to push the stopper 33 to completely disengage from the upper portion 7.
A plurality of teeth 43 are formed on an inner surface of the arc-shaped portion 37 of the stopper 33, which teeth are provided to be able to engage with a plurality of respective recesses 44 formed on a circumference of a bottom of the upper portion 7 to prevent the rotation of the upper portion 7. Those skilled in the art will understand that, in order to prevent the rotation of the upper portion 7, merely one tooth needs to be formed on the inner surface of the arc-shaped portion 37. The plurality of teeth 43 are provided in this embodiment to demonstrate the optimal effect of locking the upper portion 7. The spring 35 is arranged and compressed under
2015267876 19 Dec 2018 the arc-shaped portion 37 of the stopper 33 to constantly apply an upward force to the stopper 33.
As best seen in Figs. 16B and 16C, when the button 32 is pressed to move inwardly, it pushes against the baffle plate 40 of the stopper 33, forcing the stopper 33 to pivot downwardly to cause the teeth 43 on the inner surface of the arc-shaped portion 37 of the stopper 33 to disengage from the recesses 44 on the bottom of the upper portion 7, which allows for rotation of the upper portion 7 relative to the transition portion 6. When the button 32 is released, as shown in Fig. 16A, the stopper 33 is forced by the spring 35 to pivot upwardly to cause the teeth 43 to engage with the recesses 44, thereby locking the upper portion 7 and preventing the upper portion 7 to rotate relative to the transition portion 6. Preferably, a depressed portion is formed on a front side of the button 32 to receive the baffle plate 40 of the stopper 33, thereby preventing the stopper 33 from swaying to the left or to the right, and providing a higher stability of the locking mechanism.
As a result of the locking mechanism discussed above, when the button 32 is pressed, the upper portion is allowed to rotate relative to the transition portion around the axis of the upper portion. When the button 32 is released, the rotation of the upper portion is prevented, thereby locking the shower head at a certain angle desired by the user. For example, the locking mechanism allows the user to adjust the position of shower head such that the shower head is facing right in front of the user when the shower head is hanged on the magnetic or metallic bar by the magnetic element of the hose nut.
Preferably, when the button 32 is released, part of the button extends beyond the one-piece housing 30 through a window formed on the one-piece housing 30, and when the button 32 is fully pressed, an outer surface of it becomes flush with an outer surface of the one-piece housing 30. Such a locking mechanism allows the shower head to be conveniently rotated and to be fixed at a certain desired angle.

Furthermore, as shown in Fig. 14B, a buffering pad 31, preferably made of rubber materials, is mounted on an outer side surface of the holder, which surface is to be attached to the holding device on the wall for hanging the shower head. In order words, the buffering pad 31 is provided between the hose nut and the wall, to provide a “soft touch” feeling when mounting the hose nut onto the wall. In addition, the buffering pad 31 is able to increase the friction between the mounted hose nut and the wall, thus reinforcing the attachment of the hose nut to the wall.
In a fifth embodiment of the present invention as shown in Fig. 18, in order to allow the hose nut to be connected to water hoses of different sizes, a hose adaptor 24 is provided and connected to the lower portion 5 of the nut body 3. The hose adaptor 24 allows for connection with water hoses of different sizes. The structures of the rest of the hose nut are identical to any one of the above embodiments.
Fig. 19 illustrates a shower system 26 according to a sixth embodiment of the present invention, which comprises a water hose assembly 25 according to any one of the above embodiments, a shower head 27 connected to the water hose assembly 25 and a holding device 10 mounted on the wall. The water hose assembly 25 comprises a hose nut 1 connected to the shower head 27 and a water hose connected to a faucet 28. The holding device 10 is provided as a metallic or magnetic bar or panel having a longitudinal slot 29 formed thereon. The at least one magnetic element 8 of the hose nut 1 is inserted into the slot 29, and is guided to slide therein as a result of the smooth surface of the slot 29. Therefore, the hose nut 1 is mounted on the holding device 10 and is slidable thereon such that its height can be easily adjusted. As magnetic attraction forces are utilized to mount the hose nut of the present invention onto the wall, the structure of the hose nut is significantly simplified compared to existing products. As a result, the weight of the hose nut is substantially reduced, such that the holding device can be mounted onto the wall simply with an adhesive, without the need for fasteners that will cause damage to the wall, such as screws or nails.
